Pore Size Distribution of a Tight Sandstone Reservoir and its Effect on Micro Pore‐throat Structure: A Case Study of the Chang 7 Member of the Xin'anbian Block, Ordos Basin, China

Pore distribution and micro pore‐throat structure characteristics are significant for tight oil reservoir evaluation, but their relationship remains unclear. This paper selects the tight sandstone reservoir of the Chang 7 member of the Xin'anbian Block in the Ordos Basin as the research object and analyzes the pore size distribution and micro pore‐throat structure using field emission scanning electron microscopy (FE‐SEM), high‐pressure mercury injection (HPMI), high‐pressure mercury injection, and nuclear magnetic resonance (NMR) analyses. The study finds that: (1) Based on the pore size distribution, the tight sandstone reservoir is characterized by three main patterns with different peak amplitudes. The former peak corresponds to the nanopore scale, and the latter peak corresponds to the micropore scale. Then, the tight sandstone reservoir is categorized into three types: type 1 reservoir contains more nanopores with a nanopore‐to‐micropore volume ratio of 82:18; type 2 reservoir has a nanopore‐to‐micropore volume ratio of 47:53; and type 3 reservoir contains more micropores with a nanopore‐to‐micropore volume ratio of 35:65. (2) Affected by the pore size distribution, the throat radius distributions of different reservoir types are notably offset. The type 1 reservoir throat radius distribution curve is weakly unimodal, with a relatively dispersed distribution and peak ranging from 0.01 μm to 0.025 μm. The type 2 reservoir's throat radius distribution curve is single‐peaked with a wide distribution range and peak from 0.1 μm to 0.25 μm. The type 3 reservoir's throat radius distribution curve is single‐peaked with a relatively narrow distribution and peak from 0.1 μm to 0.25 μm. With increasing micropore volume, pore‐throat structure characteristics gradually improve. (3) The correlation between micropore permeability and porosity exceeds that of nanopores, indicating that the development of micropores notably influences the seepage capacity. In the type 1 reservoir, only the mean radius and effective porosity have suitable correlations with the nanopore and micropore porosities. The pore‐throat structure parameters of the type 2 and 3 reservoirs have reasonable correlations with the nanopore and micropore porosities, indicating that the development of these types of reservoirs is affected by the pore size distribution. This study is of great significance for evaluating lacustrine tight sandstone reservoirs in China. The research results can provide guidance for evaluating tight sandstone reservoirs in other regions based on pore size distribution.
Cooperative Integrated Reading Composition to improve pupils’ reading comprehension achievement and motivation

The focus of the study was to determine the effect of Cooperative Integrated Reading Composition (CIRC) to improve pupils’ reading comprehension achievement and motivation. A quantitative approach with a quasi-experimental design was used for this study. Interviews were also used to support the quantitative data. A total of 54 fifth grade pupils from the district of Kalimantan, Banjar, Indonesia were involved in the study. There were 28 pupils in the experimental group and 26 pupils in the control group. Quantitative data were collected from the pre and posttests and surveys, while the qualitative data came from the interviews. The quantitative data were analyzed by using descriptive and inferential analyses. Descriptive analysis showed the frequencies, means, and standard deviation, while the inferential statistics involved an independent t-test. The findings of the pre and posttests showed that there was a significant improvement in achievement for the experimental group (M=91.96, SD=5.33) when compared to the control group (M=85.38, SD=5.28), t(52)=4.55, p<0.05. The result also showed that the level of motivation for the experimental group (M=59.96, SD=6.40) was significantly higher than the control group (M=35.92, SD=6.29), t(52)=12.16, p<0.05. Interview data indicated that pupils enjoyed reading when the teacher used CIRC in the classroom. This study showed that the use of CIRC could enhance the pupils’ reading comprehension in Bahasa Indonesia. In addition, CIRC had a positive impact on the pupils’ reading comprehension of Bahasa Indonesia in terms of achievement and motivation.
Interplanetary conditions for CIR-induced and MC-induced geomagnetic storms

We present a comparison of conditions in the interplanetary space during geomagnetic storms which are generated by 2 types of large-scale inter- planetary phenomena - co-rotating interaction region (CIR) and magnetic cloud (MC or interplanetary coronal mass ejection, ICME). We select also 2 geoeffec- tive parts of MC-compressed region ahead of the leading edge of MC (Sheath) and the body of MC. Superposed epoch analyses of interplanetary parameters during 1976-2000 are used separately: (i) for 2 epoch zero times - start and end of main phase of geomagnetic storms, and (ii) for 4 categories of solar wind - CIR (121 storms), Sheath (22), MC (113), and "uncertain" (367). Though the greatest southward IMF component is observed, on the average, in magnetic clouds, the strongest storms are generated by Sheath (but not the body of MC). In spite of large differences of parameters in various types of solar wind, the turning of IMF exerts primary control over start and end of a magnetic storm.

Mediating Effects of Organizational Citizenship Behavior on Organizational Performance: Empirical Analysis of Public Employees in Guadalajara, Mexico

While much has been written about the importance of recruiting and retaining employees displaying voluntary and spontaneous actions, few have explored the mediating effect of citizenship behaviors on organizational performance. This study examines the direct and indirect effects of transformational leadership style, public service motivation, and organizational citizenship behavior (OCB) on public organization performance. It is hypothesized that when employees perceived that a public organization is practicing a transformational leadership style (TLS), they are likely to have a favorable view on the performance of their organization, but the effect is indirect and mediated by OCB. At the same time, if employees have a strong desire to serve and improve the welfare of others, they are likely to perform beyond their job requirements and thus, likely to express a positive view on the organizational performance. A structural equation modeling was used to examine the perceptions of 1,016 public employees in the Guadalajara Metropolitan Area, Mexico. The results suggest that Mexican public employees display OCB (extra role behaviors) that will be associated with a better public organizational performance because of the higher levels of PSM (public service motivation). TLS are also associated to a better organizational performance as well as to perform OCBs. But we did not find the mediator role of OCB between TLS and the organizational performance.
Trainee Teachers Level of Willingness for Inclusive Education

Every student at the Teacher Education Institute (IPG) has now been given an inclusive education course so they know about its implementation at school. Therefore, this research looks at how far the willingness of new teachers to be placed in schools with inclusive education. It was conducted in IPG in Sabah which involved 50 trainees from 5 different courses and took the Inclusive Education subject. It is a survey of quantitative reviews and uses questionnaires for data collection. The data were analyzed using Statistical Packages for the Social Science (SPSS) to see the frequencies, percentage and mean descriptive analysis. Besides, five trainee teachers from five different courses were interviewed to identify barriers that may interfere with the trainee teachers’ willingness for inclusive education. The results showed that 86 % of the trainee teachers are ready to accept special need students without prejudice and 84 % are willing to approach and recognize special needs students in their classroom. The findings also showed that there was no significant difference in the readiness of the IPG trainee in the implementation of inclusive education based on gender namely t = -0.270 with P = 0.811 greater than 0.05 (P <0.05). The trainee teachers should be able to meet the needs of students with disabilities in school. The success of inclusive education rests on teacher preparation gearing towards inclusive education. However, continuous guidance is essential to help produce qualified teachers, especially in understanding the underlying philosophy of inclusive education.
Preliminary survey of the state of pollution of the coastal environment of Ghana

The physico-chemical state of estuaries, lagoons - open and closed - and beaches along the coast of Ghana was studied to provide base-line data for the monitoring of pollution. The main sources of pollution were identified as sewage of both industrial and domestic origin and oil in the form of tarballs. Of the 16 lagoons investigated, 12 were found polluted, 2 grossly polluted. The latter, the Korle and Chemu, serve as receptacles of industrial and domestic wastes. The estuaries were generally slightly polluted or clean . Sewage pollution of beaches was usually associated with high population areas.
A cross-national perspective on the associations of grit with career success

ABSTRACT This paper presents one of the first cross-nationally comparative studies on the economic and social returns to grit (perseverance and passion for long-term goals). Specifically, we investigated whether grit incrementally predicted objective (income) and subjective (job satisfaction) career success over and above cognitive skills and educational attainment; whether grit’s association with career success was moderated by individual characteristics; whether grit’s associations with career success varied across countries; and whether this variation could be explained by labour market conditions (unemployment rates). Multi-group structural equation models with data from 6,738 respondents from 19 countries revealed that grit was incrementally associated with income and job satisfaction in some but not all countries. Grit’s effect sizes were mostly modest, yet there were some indications for variations by education and labour market conditions. Overall, these findings suggest that the associations between grit and career success are not uniform but vary across individuals and contexts.
Egg volume, energy content and fatty acid profile of Maja brachydactyla (Crustacea: Brachyura: Majidae) during embryogenesis

Fatty-acid and energy content of Maja brachydactyla eggs at different developmental stages (recently spawned, half-developed and ready to hatch) were analysed in order to understand what is being consumed and produced during the embryonic development. Egg volume increased during development (34%, 0.187 to 0.285 mm3, N = 270) and was negatively correlated with egg energy and fatty-acid content (r = −0.80 and r = −0.46, respectively), which decreased through embryogenesis. The most consumed fatty acids were the PUFA (21.2 μg · mg dw−1), followed by the SFA (18.8 μg · mg dw−1) and MUFA (14.9 μg · mg dw−1). Palmitic (16:0), oleic (18:1n-9) and eicosapentaenoic (EPA, 20:5n-3) acids were preferentially consumed (13.14, 9.21 and 8.67 μg · mg dw−1, respectively). The fatty acid composition found in M. brachydactyla eggs reflected the habitat and omnivorous and detritivorous scanvenger diet of the adults, although the consumption of algae was more important than previously thought, at least in the area where these adults were captured. Pre-hatching eggs have a high PUFA content (64.5 μg · mg dw−1 or 46.3% of the egg fatty-acid content). We conclude that larvae of this species might need a diet rich in PUFA, particularly EPA and DHA, for successful development. From the culture perspective, live preys commonly used in aquaculture will likely require to be enriched with DHA.
Building competency in self-care for social work students: a course-based case study

ABSTRACT There is increasing recognition that social work educators must do more to ensure that social work students transitioning into the profession are prepared to engage in adept self-care practices. However, documented curricular efforts targeted at meeting this aim are few. This paper documents the impact of a credit-bearing self-care course on student (N = 40) competency about self-care. The course occurred in a social work education program at a large public institution in the United States. The researcher used a pre-experimental (e.g. pre/post) design to assess course outcomes. Results indicate significant improvements in student knowledge about self-care, skills related to engaging in self-care practices, and value related to self-care. After a review literature, this paper will provide a foundational overview of the course, delineate outcome variables and measures, explicate evaluative findings, and discuss salient implications derived from this endeavor.
Effects of «Trichoderma» Treatments on the Occurrence of Decline Pathogens in the Roots and Rootstocks of Nursery Grapevines

The growth-stimulating attributes of Trichoderma treatments (dips, soil amendments and drenches with Trichoderma products containing propagules of selected strains of Trichoderma harzianum) in grapevine nurseries, and their effect on the occurrence of fungi in roots and rootstocks of nursery grapevines, in particular fungi causing Petri disease (Phaeomoniella chlamydospora and Phaeoacremonium spp.) and black foot rot (Cylindrocarpon spp.), were compared with quintozene/procymidone treated (standard) vines. Early shoot growth of Trichoderma treated vines was visibly better than that of the control vines. Eight months after planting, at uprooting, percentage take and shoot mass of Trichoderma and standard treated vines were similar, but total root mass was significantly higher for Trichoderma treated vines. Low percentages of Cylindrocarpon spp. were isolated from the rootstocks of treated and untreated vines, while less Petri disease fungi were isolated from rootstocks of Trichoderma treated vines. Markedly fewer fungi were also isolated from the roots of Trichoderma treated vines. Incidences of Petri disease fungi in roots of Trichoderma and standard treated vines were similar, but fewer Cylindrocarpon spp. were isolated from Trichoderma treated vines. These results indicate the potential of Trichoderma treatments in grapevine nurseries for the production of stronger vines with lower Phaeomoniella/Phaeoacremonium and Cylindrocarpon infection levels.
Upper critical field in nanostructured Nb: Competing effects of the reduction in density of states and the mean free path

We show that the upper critical field in nanometer-sized Nb particles is governed by the changes in the effective Ginzburg-Landau coherence length occurring due to two competing factors: (i) the decrease in the grain size and consequent increase of disorder, and (ii) the effective decrease in the density of states at the Fermi level due to the formation of a Kubo gap. As a result, the upper critical field $({H}_{C2})$ and irreversibility fields $({H}_{\mathit{irr}})$ in nanostructured Nb show nonmonotonic grain size dependences. Between 60 and $20\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$, ${H}_{C2}$ is found to increase by 2.5 times, while there is no appreciable decrease in the superconducting transition temperature $({T}_{C})$ from its bulk value of $9.4\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. This can be ascribed to a decrease in the coherence length due to a reduction in the mean free path with decreasing size. Below $20\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$, however, ${H}_{C2}$ decreases with decreasing size. In this size range $(l20\phantom{\rule{0.3em}{0ex}}\mathrm{nm})$, there also occurs a decrease in the ${T}_{C}$ as well as the superconducting energy gap. The decrease in ${H}_{C2}$ in this regime can be ascribed to the decrease in the density of states at the Fermi level due to a quantization in the electronic energy levels.
The Origin of Stock-Market Crashes: Proposal for A Mimetic Model Using Behavioral Assumptions and An Analysis of Legal Mimicry

A number of phenomena are responsible for market crashes, but an analysis of investor behavior will tell us more than the valuation of securities on their fundamentals. In this regard, the interpretation of information seems to play a central role in these exceptional events. One specific type of mimetic behavior, called informational mimicry , sheds light on the kind of sudden, precipitous price plunges seen in 1929, 1987, and 2000. The current financial crisis certainly exhibits these mechanisms, but one of its novelties is related to a new form of herd behavior arising from the international legislative alignment of financial accounting data. In fact, the new IAS-IFRS standards have produced certain pernicious, globalized effects that may be described as "legal mimicry". Among the items most commonly blamed for this "Panurgic" behavior, Fair Market Valuation and the valuation of financial instruments appear to have been the major mechanisms involved in spreading the crisis. Indeed, they lent support to one of the causes of the current crash, via securitization.
Psychological need support as a predictor of intrinsic and external motivation: the mediational role of achievement goals

Abstract The present research sought to integrate self-determination theory and the achievement goal approach to achievement motivation by examining achievement goals as mediators of the link between psychological need support and both intrinsic and external motivation. We found support for our proposed integration, as mastery-approach and performance-approach goals were documented as partial mediators of the links between autonomy and competence need support, on the one hand, and intrinsic and external motivation, on the other. Statistical evidence was not obtained for the mediational role of performance-avoidance goals. The findings are discussed in terms of the ways in which they enrich both the self-determination and achievement goal frameworks.
INTEGRATING CHEMICAL AND BIOLOGICAL STATUS ASSESSMENT: ASSEMBLING LINES OF EVIDENCE FOR THE EVALUATION OF RIVER ECOSYSTEM RISK

This paper describes various approaches to evaluating ecological risk in rivers affected by multiple chemical stressors, with emphasis on biofilm and invertebrate community responses. Metrics should be considered as different lines of evidence that, when weighted, form an advanced weight of evidence approach to establishing the environmental risk on a basin scale. Combination of field surveys to obtain observational data of communities, in situ experiments, toxicological sediment tests and a good chemical description of the medium (water and sediment) helps give an integrative view of the chemical and biological state of a river ecosystem. The greater and more distinct the variables used, the greater is our ability to identify the effects of major stressors impairing communities. Weight of evidence is an integrative methodology for tackling the challenge of determining causal relations and applying this knowledge in the decision-making processes of river management.
A Probability Electrical Resistivity Tomography Imaging of complex tectonic features in the Kissamos and Paleohora urban areas, Western Crete (Greece).

A number of 2D Electrical Resistivity Tomographies (ERT) were conducted in northwest and southwest Crete with the aim to model geotectonic features at selected urban sites. The study area is located within the central forearc of the Hellenic subduction zone. Thirteen ERT profiles were realized using the dipole–dipole electrode and/or the Wenner-Schlumberger arrays . In order to model the resistivity distribution, the probability-based electrical resistivity tomography inversion (PERTI) method has been applied . The main features of the PERTI method are: (i) unnecessity of a priori information; (ii) full, unconstrained adaptability to any kind of dataset, including the case of nonflat topography; (iii) independence from data acquisition techniques and spatial regularity; (iv) capability to resolve complex continuous resistivity variation. Since the present case-study is the first application of the PERTI algorithm to locate fault zones and near subsurface irregularities, its routine has been tested using the well-known RES2DINV commercial software as reference. The comparison has shown a common coherence between the results of the two inversion methods and confirmed the better filtering capacity and greater versatility of the PERTI algorithm, already outlined in a number of previous papers dealing with archaeological applications.
