One hundred and nine soil samples were collected in 69 different localities along two transects, one North-South, about 900 km in length, and the other East-West (750 km in length), across Senegal and Gambia. The first transect followed a rainfall gradient and the second a human density gradient. The relationship between carbon content, C/N ratio and soil type on the abundance and species distribution of the nematodes along the transects was studied. Results showed that short-term fallows did not influence the specific structure of the communities, when compared with the nematode communities of fields located in the immediate vicinity, where Scutellonema cavenessi and Tylenchorhynchus gladiolatus were the dominant species. The expected negative influence of human disturbance on nematode occurrence seemed to be compensated by greater crop diversity, mainly near the towns. Less-disturbed areas also maintained a high diversity, but were characterized by the presence of particular species such as Xiphinema spp. Soil type was the most important factor affecting the species composition of the nematode community. As a result, nematode communities followed a distribution in areas, corresponding to the successive soil types, but did not change in relation to the human or climatic gradients. At a large scale, the study of plant-parasitic nematodes can give both different and complementary information on the ecological trends of an area to that of free-living nematodes.

Purpose The purpose of this paper is to investigate the effects of values of materialism on cognitive and affective impulsiveness and responsible financial behavior among young adults. Design/methodology/approach A large-scale study (n = 483) was conducted on a sample of young adults 18 to 25 years of age in Croatia. Findings The research found that materialism has no direct effect on responsible financial behaviour (RFB), however, cognitive impulsiveness fully mediates the relationship of all three there three elements of materialism, centrality, success and happiness and RFB. Affective impulsiveness has no effect on the relationship. Furthermore, only materialism as centrality strongly and positively influences cognitive and affective impulsiveness. Practical implications Presented conclusions could be used by policymakers as guidelines for developing educational plans and curriculum to build financial capability and consumer protection among young adults and could be helpful for brand management activities targeting young people purchase decisions. Originality/value This paper’s ultimate purpose is to uncover the mechanism and the power of materialism on impulsiveness and responsible financial behavior. The paper’s originality is established by the focus on the investigation of materialism as an antecedent factor of impulsiveness and by questioning the nature of the relationship between materialism and responsible financial behavior through the mediating effect of impulsiveness.

This study examines the connection between governance, financial performance, and financial difficulties of 27 conventional private banks during the pe3riod of 2015-2018. In order to meet the accuracy of the model in the regression analysis, the Lagrange Multiplier test was previously performed so that the Fixed Effects model was chosen. The relationship of insider ownership with ROA tends to be in the shape of inversed-U and the relationship between institutional ownership and ROA is significantly positive. The relationship between ROA and financial difficulties is significantly negative. Older or established large scale banks tend to have high ROA. This happens because the greater the assets, the healthier the cash flow of the bank, so that the potential for return of asset is quite high and financial difficulties tend to be low or avoidable.

In the decade and a half since economic liberalization began in Jordan, a little noticed but large-scale organizing trend has taken over the formal provision of social welfare, redefining the institutional conception of familial identity in the process. For over one third of the population, kin solidarities have been reorganized, formalized, and registered as nongovernmental organizations in an attempt to cope with the removal of basic social provisioning by the state. Although kinship clearly has been a major element in Jordan's history, the present phenomena alter traditional familial institutions, change kin lineages, and institutionalize the economic salience of family relations. In turn, the relationship of the populace to the state has changed, marginalizing previously regime-supporting groups and facilitating the implementation of economic neoliberalism without significant protest. Repackaged as charitable elements of civil society, these family associations are sanctioned and encouraged by the state and international community. Although they are not regime creations, family associations reinforce the Jordanian regime's efforts at political deliberalization. The new elites who head the organizations have been placated through indirect incorporation into the regime; they now wield significant economic power over fellow kin and have enhanced social status backed by the new group. Furthermore, the trend mainly consists of families without immediate ambitions of entering national politics. These are not the traditional elite families.

A large-scale, community-based survey was done to assess the frequency of a wide variety of sexual behaviors in normal preadolescent children and to measure the relationship of these behaviors to age, gender, and socioeconomic and family variables. A sample of 880 2-through 12-year-old children screened to exclude those with a history of sexual abuse were rated by their mothers using several questionnaire measures. The frequency of different behaviors varied widely, with more aggressive sexual behaviors and behaviors imitative of adults being rare. Older children (both boys and girls) were less sexual than younger children. Sexuality was found to be related to the level of general behavior problems, as measured by the Achenbach Internalizing and Externalizing T scores and to a measure of family nudity. It was not related to socioeconomic variables.

Nematodes of the genus Macropostrongyloides inhabit the large intestines or stomachs of macropodid (kangaroos and wallabies) and vombatid (wombats) marsupials. This study established the relationships of seven species of Macropostrongyloides using mitochondrial (mt) protein amino acid sequence data sets. Phylogenetic analyses revealed that species of Macropostrongyloides (M. lasiorhini, M. baylisi, M. yamagutii, M. spearei, M. mawsonae and M. woodi) from the large intestines of their hosts formed a monophyletic assemblage with strong nodal support to the exclusion of M. dissimilis from the stomach of the swamp wallaby. Furthermore, the mitochondrial protein-coding genes provided greater insights into the diversity and phylogeny of the genus Macropostrongyloides; such data sets could potentially be used to elucidate the relationships among other parasitic nematodes of Australian marsupials.

The purpose of the study is to examine the longitudinal trajectories of five selected South American countries in the period between 1990 and 2018, applying the Quintuple Helix Innovation Model (QHIM). The aim is to analyse the trends of each country through the relationship of its helices using indicators extracted from an international database in order to establish their articulation and synergies to go in search of sustainable development. Within this dynamic, Venezuela represents the axis country of the study and Argentina, Chile, Colombia, and Peru make up the group that allows the comparison. The research focuses attention on two periods of Venezuelan politics since they allow measuring the variations of the countries under study. The base year is 1996 and is called the pre-Hugo Chávez Frias (HCF) period; the cutoff year for the comparison is 2014 and is called the post-HCF period. The study is longitudinal and descriptive. For the analysis, the five knowledge subsystems (helices) of the QHIM were redefined in order to have precise concepts; a database was designed based on World Bank indicators that were later thematically related to each of the helices. The interrelationships between the helices of each country were also specified in order to determine which were the weakest and which had the most positive or negative influence. In order to calculate the percentage variation of the countries, the Data Envelopment Analysis (DEA) method was applied. In this sense, the most relevant finding is related to the decisions made in the last twenty years from the political helix in Venezuela because it deactivated and disarticulated the others, causing that country to collapse.

Gold mineralization on the Marn property, Yukon, occurs in two pyroxene skarn bodies, which are adjacent to the Mount Brenner Stock in the Ogilvie Mountains. The skarns are separated by a 600 m wide monzonite intrusion and show contrasting mineralogical and geochemical characteristics in addition to quite different metal values. Significant but uneconomic Au, Ag, W, and Cu mineralization is found in skarn on the north side of the intrusion, while very low Au grades (0.052 g/t) occur at the southern contact. The mineral assemblages of both skarns are dominated by iron-rich pyroxenes. The iron content of the pyroxenes varies between Hd40 and Hd80 in the northern location and Hd80 and Hd100 in the southern skarn. A well-developed sequence of retrograde alteration affected only the northern skarn. This was probably the result of porosity and permeability differences in the early, high-temperature pyroxene skarn, which permitted greater fluid–rock interaction in the northern skarn during cooling. A small volume of diopsidic, aluminous, wollastonite-bearing skarn occurs in both the northern and southern localities. The relationship of this type of skarn to the hedenbergitic skarn is ambiguous, since there is no large-scale mineralogical zoning. The Marn is similar to hedenbergitic, auriferous skarns of Japan, where the oxidation state of the intrusive rocks is believed to be the controlling factor in the development of skarn mineralogy.

The importance of the Clear Fork Focus as a pre-pottery archaeological complex of north-central Texas has become generally known to archaeologists through the industry of its discoverer and principal proponent, Dr. Cyrus N. Ray, of Abilene, Texas. Unfortunately, the relationship of this complex to other and comparable archaeological cultures of Texas has been largely neglected and some regrettable misinformation in regard to its chronological position has been widely disseminated. In this paper the cultural affiliations and age of the Clear Fork Focus will be discussed in terms of the evidence presented by its discoverers and from the standpoint of new data derived from large scale excavations completed by the University of Texas in the terraces of the Colorado River near Austin, Texas. Additional information obtained by the writer through study of some twelve thousand projectile points from central, south, and western Texas, and their geographic and temporal distribution also is used.

The relationship of the metopes to the architecture of the peristasis of the Hephaisteion and the Parthenon is examined in order to ascertain the extent of planning which took place before the erection of a Classical Greek temple. All relevant published measurements are taken into consideration and critically compared. On the basis of the discrepancies of the corresponding architectural and sculptural members, it is argued that the working-out of the details of the plan was not the result of large-scale drawings, but was affected after the commencement of construction. While the Hephaisteion is built largely in accordance with the conventions of a Classical Doric temple, the Parthenon, due to its unique plan, provides indications of experimentation inferred from the extensive inconsistencies at its eastern end.
