Quantitative data were collected in 101 vegetational stands in two regions considered to be representative of dune sand vegetation within the grassland zone of Saskatchewan. The purpose was to ascertain species distributional patterns and to attempt to relate these distributions to environmental factors. The data were used to establish two ordinations, one based on physiographic types and the other on compositional similarities between the stands. Areas of active erosion and deposition are dominated by rhizomatous species, particularly Agropyron spp. and Psoralea lanceolata. Juniperus horizontalis is prominent in stabilized blowouts, while stabilized dunes support grassland dominated by Stipa comata, Carex eleocharis, and Koeleria cristata. The most mesic sites, dune depressions and sand flats, are occupied by Carex heliophila and Agropyron spp. with a shrubby overstory of Symphoricarpos occidentalis, Rosa woodsii, and Prunus virginiana. Factorial gradients involved in the distributional patterns include a moisture gradient ranging from xeric to mesic and a stability gradient ranging from active complexes to stabilized areas. The existence of these gradients and the intergradation of the species behavioral patterns offer strong evidence of the continuous nature of dune sand vegetation in Saskatchewan.

Unsubsidised private retirement resorts in South Africa developed during the last three decades present residents with many challenges. There is no existing generally accepted knowledge base or guidelines to serve this sensitive market. The research objective was to establish which elements are experienced by residents of retirement resorts as satisfactory and which as problematic. A literature study was also undertaken. Quantitative as well as qualitative data were obtained by means of structured questionnaires, interviews and a seminar. The results reported pertain to eight resorts in the east of Pretoria, four in Bloemfontein and two in Knysna. The study is currently being extended to other centres. The quantitative data is arranged in order of the priorities set by the biggest group (Pretoria), with the other groups in comparison. So the research was based on the sourcing of quantitative and qualitative data, as well as on descriptive evaluations. The results offer insightful knowledge and guidelines towards establishing an optimal profile for the development of long-term sustainable private retirement resorts. The implications and value of this study are that both developers of retirement resorts and prospective residents are provided with guidelines to better equip them to evaluate a specific retirement resort with regard to the sustainable well- being of residents long-term.

Species composition in floodplains is often affected by different structuring factors. Although floods play a key ecological role, habitat selection in the dry periods may blur patterns of biodiversity distribution. Here, we employed a partitioning framework to investigate the contribution of turnover and nestedness to β-diversity patterns in non-arboreal amphibians from southern Pantanal ecoregion. We investigated whether components of β-diversity change by spatial and environmental factors. We sampled grasslands and dense arboreal savannas distributed in 12 sampling sites across rainy and dry seasons, and analysed species dissimilarities using quantitative data. In the savannas, both turnover and nestedness contributed similarly to β diversity. However, we found that β diversity is driven essentially by turnover, in the grasslands. In the rainy season, balanced variation in abundance was more related to altitude and factors that induce spatial patterns, whereas dissimilarities were not related to any explanatory variable during dry season. In the Pantanal ecoregion, amphibian assemblages are influenced by a variety of seasonal constraints on terrestrial movements and biotic interactions. Our findings highlighted the role of guild-specific patterns and indicated that mass effects are important mechanisms creating amphibian community structure in the Pantanal.

Shared Psychotic Disorder

Shared psychotic disorder, characterized by shared delusion among two or more subjects (termed “Folie à deux,” “trois,” etc.), is often associated with strong religious beliefs or social isolation, factors creating strong psychological sympathy. Recently, we treated a rare familial case of “Folie à quatre” in central Tokyo without such influences. The proband was a schizophrenia patient and younger brother within monozygotic twins. Positive symptoms were “transmitted” to remaining family members, his elder brother, mother, and father father, in a relatively short period of three months. Although the pathophysiology of these positive symptoms (delusions and hallucinations) remains unclear, the transmission pattern suggests the primacy of social and environmental factors (and/or their interaction), while genetics appeared less influential in this “Folie à famille.” Although undiagnosed psychoses in the whole family cannot be excluded, they did not share the other negative schizophrenia symptoms of the proband. A strong familial connection appeared to be the most important factor for the common delusion and hallucination.

Dermatoglyphic Traits

Dermatoglyphic characters vary widely and are unaffected by age, gender and least by environment. Unlike configurations and their distinctiveness with every individual, it also shows bilateral, bisexual and population variations. Palm prints once created are unchangeable throughout life and are unaffected by environmental factors. This paper is based upon the palmar dermatoglyphic. The study reports on bisexual and bilateral palm prints among Lodhis and Thakurs of Rudahi village of Bakshi Ka Talab, Lucknow District. The palmar dermatoglyphic traits have been analyzed among the two populations which are Main line Formula, Endings of main lines D and A, Position of Axial triradius, Angle atd, Main line Index, Hypothenar, Thenar/ Ist Interdigital area, IInd Interdigital area, IIIrd Interdigital area, IVth Interdigital area, and Palmar Ridge Counts. The prints have been obtained by using the duplicating ink method on white paper. On the perusal of Principal Main line Formula among Lodhis and Thakurs, it has been noticed that the frequency is more in Lodhi males than females in formula 11.9.7. On the other hand, the frequency of Thakur males is more than Thakur females in formula 9.7.5. The Ending of Main Line D in position 11 as clearly indicated in Lodhis is higher in both the genders in comparison to Thakurs, while the position 9 indicates highest frequency in Thakur females. The Ending of main line A at position 5’ has higher frequency in Lodhi males. The Main line index value 16 is observed higher in Lodhis in comparison to Thakurs. Higher frequency has been observed in Lodhis than Thakurs in Axial triradius in modal type‘t’. The range of Angle atd is observed to have higher frequency in 36º- 40º among the Lodhis as compared to Thakurs. The palmar ridge counts mean, is found higher in Lodhi females and Thakur males. Thus this paper shows the similarity and dissimilarity among the males and females of Thakurs and Lodhis in Palmar dermatoglyphics.

In this paper we will describe the historical development of the Spanish doublet ante-antes (‘before’) and explore the question whether a process of exaptation is involved (cf. Lass 1990). We will argue that the final –s of antes, that originally marked the adverbial status of the word, in the course of time had become a kind of morphological ‘junk’ (cf. Lass 1990) and, subsequently, could be exploited in order to encode the semantic opposition between temporal meaning on the one hand, and adversative meaning on the other hand. However, based on quantitative data we will show that the incipient semantic redistribution over the course of the 16th century rather suddenly collapsed, leading to a differentiation between the prepositional ante and adverbial antes.

Organisms can develop different kinds of asymmetry when deviations from expected perfect symmetry occur. Among others are fluctuating asymmetry (FA) and directional asymmetry (DA). FA represents small random differences between corresponding parts on the left and right sides of an individual in bilaterally paired structures. It is thought that FA reflects an organism’s ability to cope with genetic and environmental stress during growth. DA occurs whenever one side on the plane of symmetry develops more than the other side, and has a genetic component. In this research, we examined the expression of morphological symmetry in 38 skulls of different age groups of wild boar (Sus scrofa), on their ventral aspect, using two-dimensional coordinates of 27 landmarks. Analyses showed the presence of significant FA and DA in the entire sample, detecting also distinctive differences between age groups. The obtained results show that the shape differences in different age groups could reasonably be a consequence of a response to environmental factors for FA and a masticatory lateralization for DA.

The objective of the present study was to evaluate the effect of the grade of crossbreeding (Lacaune x Manchega) and environmental factors on milk production in a commercial flock in Spain. A total of 5769 milk production records of sheep with different degrees of purity of the Lacaune breed crossed with Manchega were used as follows: 100% Lacaune (n = 2960), 7/8 Lacaune (n = 502), 13/16 Lacaune (n = 306), 3/4 (n = 1288), 5/8 Lacaune (n = 441) and 1/2 Lacaune: Manchega (n = 272). Additional available information included the number of parity (1 to 8), litter size (single or multiple), and the season of the year of lambing (spring, summer, autumn and winter). A mixed model was used to evaluate the level of crossbreeding and environmental factors on milk production. The 100% Lacaune sheep presented the highest milk production with respect to the F1 Lacaune x Manchega sheep (p < 0.01), showing that as the degree of gene absorption increases with the Manchega breed, it presents lower milk yield. The 100%, 13/16, and 3/4 Lacaune genotypes had the highest milk yields with respect to the 1/2 Lacaune/Manchega breed (p < 0.001). The Lacaune registered on average 181.1 L in a period adjusted to 160 days of lactation (1.13 L/ day). Likewise, the parity number, litter size, and season of lambing effects showed significant differences (p < 0.01). It was concluded that 13/16 and 3/4 Lacaune/Manchega ewes presented the highest milk yields with respect to the other crosses.

AbstractThis paper examines judicial leadership on the UK Supreme Court. It does not confine itself to the formal roles of the President and Deputy President. Rather, building on existing categories of judicial leadership, including administrative, jurisprudential and community leadership, it considers the contributions of all 12 Justices. In so doing, it provides a significant compilation of quantitative data on the activities of the Justices of the Supreme Court both on and off the bench from the the Court's inception in 2009 to the end of the 2014-2015 legal year. From this, we suggest that while a number of the Justices engaged in one or two broad forms of leadership – with Lady Hale in particular demonstrating a substantial degree of leadership across all three dimensions – at the other end of the spectrum, at least on the measures used in this paper, a significant minority did not. In the light of this, and the significant number of recent and forthcoming retirements from the Court, the paper concludes by considering the implications of our findings for the future of the Court. We argue that these retirements will result in gaps in both formal and informal judicial leadership, and it is vital that these gaps are filled by appointees who are capable of, and prepared to step up to, diverse and varied forms of judicial leadership.

Adoption Model

This chapter explores the factors impacting small to medium-sized enterprises’ (SMEs) adoption of broadband. It argues that information and communication technologies (ICTs) are highly differentiated technologies for which there is not necessarily a single adoption model. While most large European companies are connected to broadband, SMEs’ connectivity is lagging behind. The question of why one SME adopts broadband while the other does not is still understudied. Therefore, the purpose of this chapter is to fill this gap by investigating the technological, organizational, and environmental factors impacting SMEs’ adoption of broadband. This chapter starts by highlighting the importance of ICT innovations adoption in general and broadband in particular. Based on the ICT innovations adoption literature, SMEs’ broadband adoption framework will be developed and empirically validated involving nine SMEs’ key decision makers in the northwest of England. Finally, implications for researchers, practitioners, ICTs’ vendors, and policy makers will be discussed.
