Japanese law is going ‘pop’. Since the turn of the century, Japanese popular culture, especially prime-time television, has dedicated more time to legal themes, characters and settings. Lawyers, overwhelmingly women, are the heroes in both dramatic and comedic television series (Nakamura, 2007). Courtroom battles are the scene for plot developments (Ishikawa, 2004). Practising lawyers are the new celebrities, joining actors and singers on the light entertainment talk show circuit. To be sure, law is not a new thematic preoccupation on Japanese network television. Nor is it one that has become so dominant that it overshadows more traditional genres such as workplace romantic comedies, coming-of-age dramas or family soap operas (eg, Dissanayake, 2012, p._194). But, its growing presence on the silver screen in twenty-first-century Japan is a trend that merits analysis. The purpose of this chapter is to explore that socio-legal significance. This presents theoretical and empirical challenges. Theoretically, is there explanatory potential in the link between law and popular culture in Japan? Empirically, does the greater embrace of law-related characters, plots and scenes in prime-time television series since 2001 provide compelling evidence of changing popular attitudes to law and legal process among Japanese viewers? The inspiration for both the title and theme of this chapter comes from Sherwin’s When Law Goes Pop (2000). But it departs from Sherwin in how it defines and analyses the issues. For Sherwin, ‘pop’ means ‘implosion’.

The technique of friction stir welding (FSW) puts effective use frictional heat for the purpose of joining metallic materials. In this research article, we present and discuss an experimental method to determine the coefficient of friction during FSW. The experiments were conducted to study the interaction between the FSW tool (a die steel) and the base metal (a high strength aluminum alloy) at various contact pressures (13MPa, 26MPa, and 39MPa) and rotation speeds (200rpm, 600rpm, 1000rpm, and 1400rpm). The experimental results, the microstructure, and the process temperature reveal the experimental setup to be capable of simulating the conditions during FSW. The coefficient of friction was found to vary from 0.15 to 1.4, and the temperature increased to as high as 450C. The coefficient of friction was found to increase with temperature. There exists a critical temperature at which point a steep increase in the coefficient of friction was observed. The critical temperature decreases from 250C at a contact pressure of 26MPa to 200C at contact pressure of 34MPa. Below the critical temperature at a specific contact pressure the maximum coefficient of friction is 0.6, and above the critical temperature it reaches a value as high as 1.4. The steep increase in the coefficient of friction is found to be due to the seizure phenomenon and the contact condition during FSW between the tool and the workpiece (base metal) is found to be sticking.

This dissertation provides a synchronic grammatical description of Mauwake, a Papuan (Trans-New Guinea) language of about 2000 speakers on the North Coast of the Madang Province in Papua New Guinea. The theoretical background is that of Basic Linguistic Theory (BLT), used extensively in analysing and writing descriptive grammars. The chapters from morphology to clause level are described from form to function; in the later chapters the function is taken more often as the starting point. Any theory-specific terminology is kept to the minimum and formalisms have been avoided in accordance with BLT principles. Mauwake has a classic 5-vowel system and 14 consonant phonemes. With its simple phonology it is a typical representative of the Madang North Coast languages. For a Papuan language there are relatively few morphophonological alternations. Nouns are either alienably or inalienably possessed. There is no obligatory number marking in nouns or noun phrases. Pronouns have several different forms: five for case and three for other functions. The dative pronouns are treated as [+human] locatives, and they have also grammaticalised as possessives. The verbal morphology is agglutinative and mainly suffixal. Unusual features include two distributive suffixes, and the interaction of the derivational benefactive and the inflectional beneficiary suffixes. The applicative suffix has either transitivising or causative but not benefactive function. The switch-reference system distinguishes between simultaneous and sequential action, as well as same or different subject in relation to the following clause. There are several verbs denoting coming and going, and they may combine with one of three prefixes to indicate bringing and taking. Mauwake is a nominative-accusative type language, and the basic constituent order in a clause is SOV. Subject and object are the only syntactic arguments. There is no indirect object, but a clause can have two or even three objects. A nominalised clause with a finite verb functions as a relative clause or a complement clause; one with a nominalised verb has several different functions. Functional domains described include modality, negation, deixis, quantification, possession and comparison. As there are four negators, Mauwake has more variation in negative expressions than is usual in Papuan languages. Clause chaining is the preferred strategy for joining clauses into sentences, but coordination and subordination of finite clauses are also common. The form of a complement clause depends on whether it is of the fact, action or potential type. Tail-head linkage is used as a cohesive device between sentences. The discourse-level features described are topic and focus.

Reproductive rate is a major contributing factor to the profitability of a sheep meat enterprise. Low reproduction rate is a feature of sheep husbandry in semi-arid Queensland. High ambient temperatures are implicated in poor fertility (Moule 1970) where variation in response can be due to breed and to animals within a breed (Hopkins and Stephenson 1978). Breeds recently imported from South Africa were selected in arid environments and may be better adapted to pastoral conditions of northern Australia than traditional breeds.

This study will investigate (a) the thermoregulatory ability of Damara, Dorper, Poll Dorset, Rambouillet, South African Meat Merino and Queensland medium wool Merino rams prior to joinings in the autumn and spring of 1999, 2000 and 2001 and (b) the association between thermoregulatory parameters (rectal temperature and respiration rate) and ewe fertility. Results for the initial autumn joining are reported in this paper.

Considerable concern has been expressed by the Australian wool industry regarding the contamination of the clip with coloured or kempy fibres from imported breeds of sheep. As part of the evaluation of imported sheep meat breeds in western Queensland, a study is examining fibre growth and transfer of fibres and the potential to cause physical contamination of Merino fleeces. The breeds of concern in this study are the Damara, a fat-tailed breed with a hairy, coloured fleece and the Dorper which has both pigmented fibres and a kempy fleece which is shed cyclically. Three groups of Merino 27 ewes were mated to Merino, Damara and Dorper rams respectively and fibre transfer to the Merino ewes during mating, from lambing to weaning and during grazing, assessed. Both a direct field method and a laboratory method (Hatcher 1995) are being used. Those measured by direct count were measured immediately after joining and 2, 4 and 8 weeks subsequently. and the other ewes were shorn and sampled and measured in the laboratory using the dark fibre detector. This paper presents preliminary findings of those ewes monitored by the direct field method.

Sheep in western Queensland have been predominantly reared for wool. When wool prices became depressed interest in the sheep meat industry, increased. For north west Queensland producers, opportunities may exist to participate in live sheep and meat export to Asia. A simulation model was developed to determine whether this sheep producing area has the capability to provide sufficient numbers of sheep under variable climatic conditions while sustaining the land resources. Maximum capacity for sustainability of resources (as described by stock numbers) was derived from an in-depth study of the agricultural and pastoral potential of Queensland. Decades of sheep production and climatic data spanning differing seasonal conditions were collated for analysis. A ruminant biology model adapted from Grazplan was used to simulate pregnancy rate. Empirical equations predict mortalities, marking rates, and weight characteristics of sheep of various ages from simple climatic measures, stocking rate and reproductive status. The initial age structure of flocks was determined by running the model for several years with historical climatic conditions. Drought management strategies such as selling a proportion of wethers progressively down to two-tooth and oldest ewes were incorporated. Management decisions such as time of joining, age at which ewes were cast-for-age, wether turn-off age and turning-off rate of lambs vary with geographical area and can be specified at run time. The model is run for sequences of climatic conditions generated stochastically from distributions based on historical climatic data correlated in some instances. The model highlights the difficulties of sustaining a consistent supply of sheep under variable climatic conditions.

Material and immaterial security. Households, ecological and economic resources and formation of contacts in Valkeala parish from the 1630s to the 1750s. The geographical area of the thesis, Valkeala parish in the region of Kymenlaakso, is a very interesting area owing to its diversity, both in terms of natural setting and economic and cultural structure. The study begins by outlining the ecological and economic features of Valkeala and by analysing household structures. The main focus of the research lies in the contacts of the households with the outside world. The following types of contacts are chosen as indicators of the interaction: trade and credit relations, guarantees, co-operation, marriages and godparentage. The main theme of the contact analysis is to observe the significance of three factors, namely geographical extent, affluence level and kinship, to the formation of contacts. It is also essential to chart the interdependencies between ecological and economic resources, changes in the structure of households and the formation of contacts during the period studied. The time between the 1630s and the 1750s was characterized by wars, crop losses and population changes, which had an effect on the economic framework and on the structural variation of households and contact fields. In the 17th and 18th centuries Valkeala could be divided, economically, into two sections according to the predominant cultivation technique. The western area formed the field area and the eastern and northern villages the swidden area. Multiple family households were dominant in the latter part of the 17th century, and for most of the study period, the majority of people lived in the more complex households rather than in simple families. Economic resources had only a moderate impact on the structure of contacts. There was a clear connection between bigger household size and the extent and intensity of contacts. The jurisdictional boundary that ran across Valkeala from the northwest to the southeast and divided the parish into two areas influenced the formation of contacts more than the parish boundaries. Support and security were offered largely by the primary contacts with one s immediate family, neighbours and friends. Economic support was channelled from the wealthier to the less well off by credits. Cross-marriages, cross-godparentage and marital networks could be seen as manifestations of an aim towards stability and the joining of resources. It was essential for households both to secure the workforce needed for a minimum level of subsistence and to ensure the continuation of the family line. These goals could best be reached by complex households that could adapt to the prevailing circumstances and also had wider and more multi-layered contacts offering material and immaterial security.

Experimental results pertaining to the initiation, dynamics and mechanism of cavitation erosion on poly(methyl methacrylate) specimens tested in a rotating disk device are described in detail. Erosion normally starts at the location nearest to the center of rotation (CR). As the exposure time to cavitation increases, additional erosion areas or sites appear away from the CR and secondary erosion (induced by eroded pits) spreads upstream and merges with the main pit. The microcracks increase in density towards the end of the incubation period and transform into macrocracks in most cases. A study of light optical photographs and scanning electron micrographs of the eroded area shows that material particles are removed from the network of cracks because of crack joining and pits indicate particle debris. Optical degradation (loss of transmittance) is observed to be greater on the back of the specimen than on the front.

The leader protease (L-pro) and capsid-coding sequences (P1) constitute approximately 3 kb of the foot-and-mouth disease virus (FMDV). We studied the phylogenetic relationship of 46 FMDV serotype A isolates of Indian origin collected during the period 1968-2005 and also eight vaccine strains using the neighbour-joining tree and Bayesian tree methods. The viruses were categorized under three major groups - Asian, Euro-South American and European. The Indian isolates formed a distinct genetic group among the Asian isolates. The Indian isolates were further classified into different genetic subgroups (<5% divergence). Post-1995 isolates were divided into two subgroups while a few isolates which originated in the year 2005 from Andhra Pradesh formed a separate group. These isolates were closely related to the isolates of the 1970s. The FMDV isolates seem to undergo reverse mutation or onvergent evolution wherein sequences identical to the ancestors are present in the isolates in circulation. The eight vaccine strains included in the study were not related to each other and belonged to different genetic groups. Recombination was detected in the L-pro region in one isolate (A IND 20/82) and in the VP1 coding 1D region in another isolate (A RAJ 21/96). Positive selection was identified at aa positions 23 in the L-pro (P<0.05; 0.046*) and at aa 171 in the capsid protein VP1 (P<0.01; 0.003**).

This thesis studies the experiences of women who have lived in a youth home as girls. There are two main themes: 1) experiences of living in a youth home, and 2) experiences of coping as an adult. Data on the first theme is purely subjective; it derives from personal, recalled experiences. Data on the second theme is partly based on experiences and partly on facts about the current life situation of the research participants. A third theme of the thesis is concerned with the question of how the research participants’ placement in a youth home influenced their later life. The thesis contributes valuable knowledge concerning the experiences of young people who have been raised in substitute care, a topic that is rare in the literature. The empirical data of the study consists of responses to an initial inquiry and subsequent interviews. The inquiry was sent to 116 former inhabitants of a youth home. 62 altogether returned the inquiry, and 34 participated in the interview. The purpose of the inquiry was to produce an overview of the life situations of the research participants and to invite them to participate in the interview. In addition, the inquiry sought to produce an overview of how the participants enjoyed living in a youth home and how they saw its significance in terms of their later lives. The interviews concentrated on the research participants’ experiences concerning the processes of getting into a youth home, living there, and coping independently in life afterwards. The most central result relating to the first main theme was that the experiences were both shared and non-shared. Living in a youth home was characterized by six general sentiments: “wonderful, real home”, “new world!”, “safe haven”, “place to live”, “penal institution”, and “nightmare”. These sentiments seemed to be related first and foremost to whether one’s own, individual needs and expectations had been met in the youth home. The strongest and most common needs, as experienced, were the needs for safety, belongingness and respect. On the basis of the experiences, meeting these needs can be considered as the most important task of a youth home. The results relating to the second main theme of the study were examined in two different ways. Comparisons with the general female population (education, situation in working life and financial circumstances) showed that research participants had coped less well. Differences were also found to exist in family structures: nuclear families and single mother families were more unusual among research participants, and stepfamilies more common, than in the general population. More of the participants’ children than of the general population’s lived with somebody other than their parent. However, the experience of coping well was common among research participants, although the beginning of independent living had been generally experienced as difficult: feelings of loneliness, insecurity and restlessness were dominant. Later, a sense of life control developed and strengthened through joining with others (family, work, friends), through accepting one’s own life history and through creating one’s own model of living. As the most significant explanation of their coping, the research participants identified their own (innate) strength and will to cope. The majority of the research participants felt that the youth home had a positive influence on their later lives. Positive influences can be grouped in three “levels”: I) getting out of the home, II) having good experiences and learning useful things, and III) the essential effect on one’s own way of thinking and living. The second level’s influence includes strengthened self-esteem, increased social understanding and new knowledge and skills. Some research participants did not think the youth home had any significance in terms of their later lives, and some thought it had negative significance.

The genetics of heifer performance in tropical 'wet' and 'dry' seasons, and relationships with steer performance, were studied in Brahman (BRAH) and Tropical Composite (TCOMP) (50% Bos indicus, African Sanga or other tropically adapted Bos taurus; 50% non-tropically adapted Bos taurus) cattle of northern Australia. Data were from 2159 heifers (1027 BRAH, 1132 TCOMP), representing 54 BRAH and 51 TCOMP sires. Heifers were assessed after post-weaning 'wet' (ENDWET) and 'dry' (ENDDRY) seasons. Steers were assessed post-weaning, at feedlot entry, over a 70-day feed test, and after similar to 120-day finishing. Measures studied in both heifers and steers were liveweight (LWT), scanned rump fat, rib fat and M. longissimus area (SEMA), body condition score (CS), hip height (HH), serum insulin-like growth factor-I concentration (IGF-I), and average daily gains (ADG). Additional steer measures were scanned intra-muscular fat%, flight time, and daily (DFI) and residual feed intake (RFI). Uni- and bivariate analyses were conducted for combined genotypes and for individual genotypes. Genotype means were predicted for a subset of data involving 34 BRAH and 26 TCOMP sires. A meta-analysis of genetic correlation estimates examined how these were related to the difference between measurement environments for specific traits. There were genotype differences at the level of means, variances and genetic correlations. BRAH heifers were significantly (P < 0.05) faster-growing in the 'wet' season, slower-growing in the 'dry' season, lighter at ENDDRY, and taller and fatter with greater CS and IGF-I at both ENDWET and ENDDRY. Heritabilities were generally in the 20 to 60% range for both genotypes. Phenotypic and genetic variances, and genetic correlations, were commonly lower for BRAH. Differences were often explained by the long period of tropical adaptation of B. indicus. Genetic correlations were high between corresponding measures at ENDWET and ENDDRY, positive between fat and muscle measures in TCOMP but negative in BRAH (mean of 13 estimates 0.50 and -0.19, respectively), and approximately zero between steer feedlot ADG and heifer ADG in BRAH. Numerous genetic correlations between heifers and steers differed substantially from unity, especially in BRAH, suggesting there may be scope to select differently in the sexes where that would aid the differing roles of heifers and steers in production. Genetic correlations declined as measurement environments became more different, the rates of decline (environment sensitivity) sometimes differing with genotype. Similar measures (LWT, HH and ADG; IGF-I at ENDWET in TCOMP) were genetically correlated with steer DFI in heifers as in steers. Heifer SEMA was genetically correlated with steer feedlot RFI in BRAH (0.75 +/- 0.27 at ENDWET, 0.66 +/- 0.24 at ENDDRY). Selection to reduce steer RFI would reduce SEMA in BRAH heifers but otherwise have only small effects on heifers before their first joining.

A total of 2115 heifers from two tropical genotypes (1007 Brahman and 1108 Tropical Composite) raised in four locations in northern Australia were ovarian-scanned every 4-6 weeks to determine the age at the first-observed corpus luteum (CL) and this was used to de. ne the age at puberty for each heifer. Other traits recorded at each time of ovarian scanning were liveweight, fat depths and body condition score. Reproductive tract size was measured close to the start of the first joining period. Results showed significant effects of location and birth month on the age at first CL and associated puberty traits. Genotypes did not differ significantly for the age or weight at first CL; however, Brahman were fatter at first CL and had a small reproductive tract size compared with that of Tropical Composite. Genetic analyses estimated the age at first CL to be moderately to highly heritable for Brahman (0.57) and Tropical Composite (0.52). The associated traits were also moderately heritable, except for reproductive tract size in Brahmans (0.03) and for Tropical Composite, the presence of an observed CL on the scanning day closest to the start of joining (0.07). Genetic correlations among puberty traits were mostly moderate to high and generally larger in magnitude for Brahman than for Tropical Composite. Genetic correlations between the age at CL and heifer- and steer-production traits showed important genotype differences. For Tropical Composite, the age at CL was negatively correlated with the heifer growth rate in their first postweaning wet season (-0.40) and carcass marbling score (-0.49), but was positively correlated with carcass P8 fat depth (0.43). For Brahman, the age at CL was moderately negatively genetically correlated with heifer measures of bodyweight, fatness, body condition score and IGF-I, in both their first postweaning wet and second dry seasons, but was positively correlated with the dry-season growth rate. For Brahman, genetic correlations between the age at CL and steer traits showed possible antagonisms with feedlot residual feed intake (-0.60) and meat colour (0.73). Selection can be used to change the heifer age at puberty in both genotypes, with few major antagonisms with steer- and heifer- production traits.

Shear flows of inelastic spheres in three dimensions in the Volume fraction range 0.4-0.64 are analysed using event-driven simulations.Particle interactions are considered to be due to instantaneous binary collisions, and the collision model has a normal coefficient of restitution e(n) (negative of the ratio of the post- and pre-collisional relative velocities of the particles along the line joining the centres) and a tangential coefficient of restitution e(t) (negative of the ratio of post- and pre-collisional velocities perpendicular to the line Joining the centres). Here, we have considered both e(t) = +1 and e(t) = e(n) (rough particles) and e(t) =-1 (smooth particles), and the normal coefficient of restitution e(n) was varied in the range 0.6-0.98. Care was taken to avoid inelastic collapse and ensure there are no particle overlaps during the simulation. First, we studied the ordering in the system by examining the icosahedral order parameter Q(6) in three dimensions and the planar order parameter q(6) in the plane perpendicular to the gradient direction. It was found that for shear flows of sufficiently large size, the system Continues to be in the random state, with Q(6) and q(6) close to 0, even for volume fractions between phi = 0.5 and phi = 0.6; in contrast, for a system of elastic particles in the absence of shear, the system orders (crystallizes) at phi = 0.49. This indicates that the shear flow prevents ordering in a system of sufficiently large size. In a shear flow of inelastic particles, the strain rate and the temperature are related through the energy balance equation, and all time scales can be non-dimensionalized by the inverse of the strain rate. Therefore, the dynamics of the system are determined only by the volume fraction and the coefficients of restitution. The variation of the collision frequency with volume fraction and coefficient of estitution was examined. It was found, by plotting the inverse of the collision frequency as a function of volume fraction, that the collision frequency at constant strain rate diverges at a volume fraction phi(ad) (volume fraction for arrested dynamics) which is lower than the random close-packing Volume fraction 0.64 in the absence of shear. The volume fraction phi(ad) decreases as the coefficient of restitution is decreased from e(n) = 1; phi(ad) has a minimum of about 0.585 for coefficient of restitution e(n) in the range 0.6-0.8 for rough particles and is slightly larger for smooth particles. It is found that the dissipation rate and all components of the stress diverge proportional to the collision frequency in the close-packing limit. The qualitative behaviour of the increase in the stress and dissipation rate are well Captured by results derived from kinetic theory, but the quantitative agreement is lacking even if the collision frequency obtained from simulations is used to calculate the pair correlation function used In the theory.

The distribution of relative velocities between colliding particles in shear flows of inelastic spheres is analysed in the Volume fraction range 0.4-0.64. Particle interactions are considered to be due to instantaneous binary collisions, and the collision model has a normal coefficient of restitution e(n) (negative of the ratio of the post- and pre-collisional relative velocities of the particles along the line joining the centres) and a tangential coefficient of restitution e(t) (negative of the ratio of post- and pre-collisional velocities perpendicular to line joining the centres). The distribution or pre-collisional normal relative velocities (along the line Joining the centres of the particles) is Found to be an exponential distribution for particles with low normal coefficient of restitution in the range 0.6-0.7. This is in contrast to the Gaussian distribution for the normal relative velocity in all elastic fluid in the absence of shear. A composite distribution function, which consists of an exponential and a Gaussian component, is proposed to span the range of inelasticities considered here. In the case of roughd particles, the relative velocity tangential to the surfaces at contact is also evaluated, and it is found to be close to a Gaussian distribution even for highly inelastic particles.Empirical relations are formulated for the relative velocity distribution. These are used to calculate the collisional contributions to the pressure, shear stress and the energy dissipation rate in a shear flow. The results of the calculation were round to be in quantitative agreement with simulation results, even for low coefficients of restitution for which the predictions obtained using the Enskog approximation are in error by an order of magnitude. The results are also applied to the flow down an inclined plane, to predict the angle of repose and the variation of the volume fraction with angle of inclination. These results are also found to be in quantitative agreement with previous simulations.

En route from Birmingham to Syria in 2013, British-Jihadi neophytes aged 22, Yusuf Sarwar and Mohammed Ahmed purchased two books via Amazon to prepare for their mission in Syria after joining ISIS: The Koran for Dummies and Islam for Dummies. Journalists were swift to disparage their reading. The book’s author, Princeton University campus imam, Sohaib Nazeer Sultan remarked “Even though they may have ordered it, I don't think they read it.” In 1933, aged 27, Adolf Eichmann moved to Berlin to join the Sicherheitsdienst SD whereupon he read Immanuel Kant’s book the Kritik der praktischen Vernunft (The Critique of Practical Reason) for the first time. After his trial in Jerusalem, Hannah Arendt of course dismissed Eichmann’s reading of the German philosopher as thoroughly vacuous. Ever since, writers have sought to undermine the veracity of Eichmann’s account. The global Jihadis are illiterate, a journalist recently commented: they’re not well read in the Qur’an, and if they have read it, they have thoroughly misunderstood it. He cited as evidence Abdul Raqib Amin’s YouTube rhetorical: Forget everyone. Read the Koran, read the instruction of life. Find out what is jihad. Eichmann on the other hand was not illiterate in his youth. Before Berlin, he had already read Kant’s Groundwork of the Metaphysics of Morals ; he would also re-read the Critique of Practical Reason, and from his testimony and terminology we can infer he was familiar with Kantian concepts that extend beyond both books...
