Communication Interception Technology (CIT) and its use in the fight against Transnational Organised Crime (TOC) in Australia : a review of the literature

In recent times, technology has advanced in such a manner that the world can now communicate in means previously never thought possible. Transnational organised crime groups, who have exploited these new technologies as basis for their criminal success, however, have not overlooked this development, growth and globalisation. Law enforcement agencies have been confronted with an unremitting challenge as they endeavour to intercept, monitor and analyse these communications as a means of disrupting the activities of criminal enterprises. The challenge lies in the ability to recognise and change tactics to match an increasingly sophisticated adversary. The use of communication interception technology, such as phone taps or email interception, is a tactic that when used appropriately has the potential to cause serious disruption to criminal enterprises. Despite the research that exists on CIT and TOC, these two bodies of knowledge rarely intersect. This paper builds on current literature, drawing them together to provide a clearer picture of the use of CIT in an enforcement and intelligence capacity. It provides a review of the literature pertaining to TOC, the structure of criminal enterprises and the vulnerability of communication used by these crime groups. Identifying the current contemporary models of policing it reviews intelligence-led policing as the emerging framework for modern policing. Finally, it assesses the literature concerning CIT, its uses within Australia and the limitations and arguments that exist. In doing so, this paper provides practitioners with a clearer picture of the use, barriers and benefits of using CIT in the fight against TOC. It helps to bridge the current gaps in modern policing theory and offers a perspective that can help drive future research.

TV Carriage Fee Disputes Hurt Consumers the Most

More than 14 million Dish Network subscribers have been without Breaking Bad, Mad Men, and The Walking Dead since June when the satellite provider pulled AMC Networks—AMC, Sundance, IFC, and WE tv—from its lineup in a dispute over carriage fees. The tactic is called a blackout, and it’s becoming increasingly common in the television landscape as pay-TV operators and station owners battle over the nearly $5 billion at stake in the next 5 years.

Improving management of summer weeds in dryland cropping systems with Cotton

In 2001 a scoping study (phase I) was commissioned to determine and prioritise the weed issues of cropping systems with dryland cotton. The main findings were that the weed flora was diverse, cropping systems complex, and weeds had a major financial and economical impact. Phase II 'Best weed management strategies for dryland cropping systems with cotton' focused on improved management of the key weeds, bladder ketmia, sowthistle, fleabane, barnyard grass and liverseed grass.In Phase III 'Improving management of summer weeds in dryland cropping systems with cotton', more information on the seed-bank dynamics of key weeds was gained in six pot and field studies. The studies found that these characteristics differed between species, and even climate in the case of bladder ketmia. Species such as sowthistle, fleabane and barnyard grass emerged predominately from the surface soil. Sweet summer grass was also in this category but also had a significant proportion emerging from 5 cm depth. Bladder ketmia in central Queensland emerged mainly from the top 2 cm, whereas in southern Queensland it emerged mainly from 5 cm. Liverseed grass had its highest emergence from 5 cm below the surface. In all cases the persistence of seed increased with increasing soil depth. Fleabane was also found to be sensitive to soil type with no seedlings emerging in the self-mulching black vertisol soil. A strategic tillage trial showed that burial of fleabane seed, using a disc or chisel plough, to a depth of greater than 2 cm can significantly reduce subsequent fleabane emergence. In contrast, tillage increased barnyard grass emergence and tended to decrease persistence. This research showed that weed management plans can not be blanketed across all weed species, rather they need to be targeted for each main weed species.This project has also resulted in an increased knowledge of how to manage fleabane from the eight experiments; one in wheat, two in sorghum, one in cotton and three in fallow on double knock. For summer crops, the best option is to apply a highly effective fallow treatment prior to sowing the crops. For winter crops, the strategy is the integration of competitive crops, residual herbicide followed by a knockdown to control survivors. This project explored further the usefulness of the double knock tactic for weed control and preventing seed set. Two field and one pot experiments have shown that this tactic was highly effective for fleabane control. Paraquat products provided good control when followed by glyphosate. When 2, 4-D was added in a tank mix with glyphosate and followed by paraquat products, 99-100% control was achieved in all cases. The ideal follow-up times for paraquat products after glyphosate were 5-7 days. The preferred follow-up times for 2, 4-D after glyphosate were on the same day and one day later. The pot trial, which compared a population from a cropping field with previous glyphosate exposure and a population from a non-cropping area with no previous glyphosate herbicide exposure, showed that the pervious herbicide exposure affected the response of fleabane to herbicidal control measures. The web-based brochure on managing fleabane has been updated.Knowledge on management of summer grasses and safe use of residual herbicides was derived from eight field and pot experiments. Residual grass and broadleaf weed control was excellent with atrazine pre-plant and at-planting treatments, provided rain was received within a short interval after application. Highly effective fallow treatments (cultivation and double knock), not only gave excellent grass control in the fallow, also gave very good control in the following cotton. In the five re-cropping experiments, there were no adverse impacts on cotton from atrazine, metolachlor, metsulfuron and chlorsulfuron residues following use in previous sorghum, wheat and fallows. However, imazapic residues did reduce cotton growth.The development of strategies to reduce the heavy reliance on glyphosate in our cropping systems, and therefore minimise the risk of glyphosate resistance development, was a key factor in the research undertaken. This work included identifying suitable tactics for summer grass control, such as double knock with glyphosate followed by paraquat and tillage. Research on fleabane also concentrated on minimising emergence through tillage, and applying the double knock tactic. Our studies have shown that these strategies can be used to prevent seed set with the goal of driving down the seed bank. Utilisation of the strategies will also reduce the reliance on glyphosate, and therefore reduce the risk of glyphosate resistance developing in our cropping systems.Information from this research, including ecological and management data were collected from an additional eight paddock monitoring sites, was also incorporated into the Weeds CRC seed bank model "Weed Seed Wizard", which will be able to predict the impact of different management options on weed populations in cotton and grain farming systems. Extensive communication activities were undertaken throughout this project to ensure adoption of the new strategies for improved weed management and reduced risk for glyphosate resistance.

Individual-based modelling of the efficacy of fumigation tactics to control lesser grain borer (Rhyzopertha dominica) in stored grain

Increasing resistance to phosphine (PH 3) in insect pests, including lesser grain borer (Rhyzopertha dominica) has become a critical issue, and development of effective and sustainable strategies to manage resistance is crucial. In practice, the same grain store may be fumigated multiple times, but usually for the same exposure period and concentration. Simulating a single fumigation allows us to look more closely at the effects of this standard treatment.We used an individual-based, two-locus model to investigate three key questions about the use of phosphine fumigant in relation to the development of PH 3 resistance. First, which is more effective for insect control; long exposure time with a low concentration or short exposure period with a high concentration? Our results showed that extending exposure duration is a much more efficient control tactic than increasing the phosphine concentration. Second, how long should the fumigation period be extended to deal with higher frequencies of resistant insects in the grain? Our results indicated that if the original frequency of resistant insects is increased n times, then the fumigation needs to be extended, at most, n days to achieve the same level of insect control. The third question is how does the presence of varying numbers of insects inside grain storages impact the effectiveness of phosphine fumigation? We found that, for a given fumigation, as the initial population number was increased, the final survival of resistant insects increased proportionally. To control initial populations of insects that were n times larger, it was necessary to increase the fumigation time by about n days. Our results indicate that, in a 2-gene mediated resistance where dilution of resistance gene frequencies through immigration of susceptibles has greater effect, extending fumigation times to reduce survival of homozygous resistant insects will have a significant impact on delaying the development of resistance. © 2012 Elsevier Ltd.

Q-evankeliumi ja psykohistoria : Uuden testamentin eksegetiikan väitöskirja

In the course of my research for my thesis The Q Gospel and Psychohistory, I moved on from the accounts of the Cynics ideals to psychohistorical explanations. Studying the texts dealing with the Cynics and the Q Gospel, I was amazed by the fact that these texts actually portrayed people living in greater poverty than they had to. I paid particular attention to the fact that the Q Gospel was born in traumatising, warlike circumstances. Psychiatric traumatology helped me understand the Q Gospel and other ancient documents using historical approaches in a way that would comply with modern behavioural science. Even though I found some answers to the questions I had posed in my research, the main result of my research work is the justification of the question: Is it important to ask whether there is a connection between the ethos expressed by means of the religious language of the Q Gospel and the predominantly war-related life experiences typical to Palestine at the time. As has been convincingly revealed by a number of studies, traumatic events contribute to the development of psychotic experiences. I approached the problematic nature, significance and complexity of the ideal of poverty and this warlike environment by clarifying the history of psychohistorical literary research and the interpretative contexts associated with Sigmund Freud, Jacques Lacan and Melanie Klein. It is justifiable to question abnormal mentality, but there is no reliable return from the abnormal mentality described in any particular text to the only affecting factor. The popular research tendency based on the Oedipus complex is just as controversial as the Oedipus complex itself. The sociological frameworks concerning moral panics and political paranoia of an outer and inner danger fit quite well with the construction of the Q Gospel. Jerrold M. Post, M.D., Professor of Psychiatry, Political Psychology and Interna-tional Affairs at George Washington University, and founder and director of the Center for the Analysis of Personality and Political Behavior for the Central Intelligence Agency, has focused on the role played by charisma in the attracting of followers and detailed the psychological styles of a "charismatic" leader. He wrote the books Political Paranoia and Leaders and Their Followers in a Dangerous World: the Psychology of Political Behavior among others. His psychoanalytic vocabulary was useful for my understanding of the minds and motivations involved in the Q Gospel s formation. The Q sect began to live in a predestined future, with the reality and safety of this world having collapsed in both their experience and their fantasies. The deep and clear-cut divisions into good and evil that are expressed in the Q Gospel reveal the powerful nature of destructive impulses, envy and overwhelming anxiety. Responsible people who influenced the Q Gospel's origination tried to mount an ascetic defense against anxiety, denying their own needs, focusing their efforts on another objective (God s Kingdom) and a regressive, submissive earlier phase of development (a child s carelessness). This spiritual process was primarily an ecclesiastic or group-dynamical tactic to give support to the power of group leaders.

Conformationally Restricted Nucleocyclitols: a Study into their Conformational Preferences and Supramolecular Architecture in the Solid State

With the intent of probing the feasibility of employing annulation as a tactic to engender axial rich conformations in nucleoside analogues, two adenine-derived, ``conformationally restricted'' nucleocylitols, 9 and 10, have been conceptualized as representatives of a hitherto unexplored class of nucleic acid base-cyclitol hybrids. A general synthetic strategy, with an inherent scope for diversification, allowed rapid functionalization of indane and tetralin to furnish 9 and 10 respectively in fair yield. Single-crystal X-ray diffraction analysis revealed that the two nucleocyclitols under study, though homologous, present completely dissimilar modes of molecular packing, marked, in particular, by the nature of involvement of the adenynyl NH2 group in the supramolecular assembly. In addition, the crystal structures of 9 and 10 also exhibit two different conformations of the functionalized cyclohexane ring. Thus, while the six-membered carbocycle in cyclopenta-annulated 9 exists in the expected chair (C) conformation that in cyclohexaannulated 10, which crystallizes as a dihydrate, shows an unusual twist-boat (TB) conformation. From a close analysis of the (HNMR)-H-1 spectroscopic data recorded for 9 and 10 in CD3OD, it was possible to put forth a putative explanation for the uncanny conformational preferences of crystalline 9 and 10.

The effects of eutrophication on alternative reproductive tactics in threespine sticklebacks

When organisms compete for mates and fertilisations, the process of sexual selection drives the evolution of traits that increase reproductive success. The traits targeted by selection, and the extent to which they change, are constrained by the local environment. Sexual selection due to female mate choice can be undermined by alternative reproductive tactics (ARTs), which refers to discontinuous variation in traits or behaviours used in reproduction. As human activities are rapidly changing our planet, this raises the question how ARTs will be affected. Fish show a bewildering diversity of ARTs, which make them good model organisms to answer these questions. One example of human-induced environmental change, which is affecting aquatic ecosystems around the world, is eutrophication, the over-enrichment of water bodies with nutrients. One of its effects is decreased underwater visibility due to increases in both turbidity and vegetation density. The aims of this thesis were to investigate the effects increased turbidity and vegetation density have on an ART in sticklebacks, a fish common to marine and fresh water bodies of the Northern hemisphere. I furthermore investigated how this affected sexual selection for male size, a trait commonly under selection. I used a combination of behavioural observations in microcosms, where I manipulated underwater visibility, with collection of genetic material to reconstruct parentage of broods, and thus identify sneak fertilisations. The results show that turbidity might have weak negative effects on the frequency of sneaking behaviour, although this behaviour was rather infrequent in these experiments, which complicates firm conclusions. In dense vegetation the number of sneak fertilisations decreased slightly, as fewer nesting males sneaked, while the number of non-nesting males sneaking remained constant. The paternity analyses revealed that a significantly smaller fraction of eggs was sneak fertilised under dense vegetation. Furthermore, amongst the nesting males that sneaked, the amount of eggs sneak fertilised correlated positively with courtship success. A reduction in sneaking by these males under dense vegetation equalised the distribution of fertilisation success, in turn contributing to a decrease in the opportunity for selection. Under dense vegetation significantly more males built nests, which has also been observed in previous field studies. In a separate experiment we addressed if such changes in the proportion of nesters and non-nesters, without changes in visibility, affected the incidence of sneak fertilisation. My results show this was not the case, likely because sneaking is an opportunistic tactic shown by both nesters and non-nesters. Non-nesters did sneak proportionately more when there were many of them, which could be due to changes in the cost-benefit ratio of sneaking. As nesters can only attack one intruder at a time, the costs and risks per sneaker will decrease as the number of sneakers increases. The defensive behaviours shown by the nesters before spawning shifted to a more aggressive form of nest defence. This could be because less aggressive behaviours lose their effectiveness when the number of intruders increases. It could also indicate that the risks associated with aggressive behaviours decrease when there are fewer fellow nesters, as other studies indicate nesters are competitive and aggressive individuals. Under turbid conditions I did not detect changes in the opportunity for selection, based on fertilisation success, nor was male size under significant selection under clear or turbid conditions. More thorough analyses under densely vegetated conditions across the nesting, courtship and fertilisation stages revealed a decrease in the opportunity for selection across all stages. A reduction in sneaking by nesters contributed to this. During the nesting stage, but not during later stages, body size was under significant directional selection under sparse, but not dense vegetation. This illustrates the importance of considering all selection stages to get a complete picture of how environmental changes affect sexual selection. Leaving out certain stages or subgroups can result in incomplete or misleading results.

Workplace Bullying among Business Professionals - Prevalence, Organisational Antecedents and Gender Differences (summary section only)

Workplace bullying can be defined as repeated and persistent negative acts that involve a power imbalance and create a hostile work environment. Partly because of the many negative consequences associated with the phenomenon, bullying has recently become the focus of many studies by contemporary organisational researchers. Drawing on a survey, this thesis provides information on the prevalence and forms of bullying among business professionals, a group of employees neglected in previous bullying research. The thesis follows a tradition among Nordic researchers that emphasises the role of the psychosocial work environment in bullying. In particular, it illustrates how high internal competition and a high degree of organisational politics in business life may lead employees to use bullying as a tactic to gain benefits over their colleagues. Furthermore, it explores the significance of gender in bullying in male-dominated work environments, with women tending to be subjected to more negative acts, tending to feel less capable to defend themselves in these situations, and tending to feel less reluctant to classify these experiences as bullying. In addition to the introductory essay, this thesis consists of a book chapter and four articles. These five papers address particular aspects of workplace bullying: the prevalence and forms of bullying, the significance of gender in bullying, and organisational antecedents of bullying.

CHLORAL HYDRATE AS A WATER CARRIER FOR THE EFFICIENT DEPROTECTION OF ACETALS, DITHIOACETALS, AND TETRAHYDROPYRANYL ETHERS IN ORGANIC SOLVENTS

The efficient deprotection of several acetals, dithioacetals, and tetrahydropyranyl (THP) ethers under ambient conditions, using chloral hydrate in hexane, is described. Excellent yields were realized for a wide range of both aliphatic and aromatic substrates. The method is characterized by mild conditions (room temperatures or below), simple workup, and the ready availability of chloral hydrate. High chemoselectivity was also observed in the deprotection, acetonides, esters, and amides being unaffected under the reaction conditions. Products were generally purified chromatographically and identified spectrally. These results constitute a novel addition to current methodology involving a widely employed deprotection tactic in organic synthesis. It seems likely that the mechanism of the reaction involves adsorption of the substrate on the surface of the sparingly soluble chloral hydrate.

Moral e disciplina: monges e escravos no espaço monástico beneditino na Corte Imperial

Esta pesquisa trata das alterações ocorridas na propriedade dos monges da Ordem de São Bento no Rio de Janeiro. O crescimento da cidade, a falta de monges nos claustros e o aumento do número de escravos no século XIX, contribuíram para a configuração desse espaço e também nas mudanças dos preceitos religiosos. Com base a Regra de São Bento novas práticas foram apontadas nesse universo monástico exigindo maior rigor na conduta dos monges e da sua mão-de-obra cativa no cotidiano do mosteiro. Dessa forma, aponto como as transformações ocorridas na administração da Congregação Beneditina do Brasil e os interesses do Governo Imperial no patrimônio da Ordem estabeleceram uma relação de poder entre os monges e seus escravos, no período de 1819 a 1842. A partir da análise da Confraria do Rosário, constituída na capela-mor do mosteiro, ilumino o lugar dos cativos nessa nova organização, observando-a como parte de uma tática de produção de corpos submissos à moral e à disciplina.

Da Atenas Brasileira à Jamaica Brasileira: reflexões sobre processos de construção de identidades culturais da capital maranhense

Estudo sobre o processo de construção identitária da cidade de São Luís. Dos vários epítetos pelos quais a cidade é designada, são contemplados aqui apenas os de Atenas Brasileira, Única cidade brasileira fundada pelos franceses e Jamaica Brasileira. O propósito é o de identificar as condições sociais, políticas e culturais presentes no contexto específico de cada uma dessas construções. São levados em conta o modelo eurocêntrico e o elitismo cultural vigentes na sociedade de um século XIX marcado pelas categorias dominantes/dominados, cultura letrada/cultura popular próprias das condições que ensejaram o estabelecimento da Atenas Brasileira. Foi analisada a estratégia que fez de um acontecimento histórico a instauração de um ato fundador de tradição e, por extensão, de criação de identidade cultural, tática que deu a São Luís, na primeira década do século XX, a designação de Única cidade brasileira fundada pelos franceses, a mesmo tempo em que ensejou a revitalização da primeira identidade cultural. Por fim, a análise do advento da Jamaica Brasileira nos anos de 1970, identidade cultural oriunda das massas populares e periféricas da cidade de São Luís, caracterizadas pela exclusão social e negritude, de forte apelo sensível e estético marcado pelo ritmo, pela dança, pela música reggae de origem jamaicana. Esses estudos tiveram como fundamentos epistemológicos teorizações dos campos da comunicação, dos estudos culturais, memória e narrativa. Para sua realização foram efetuadas leitura e análise de material bibliográfico e documental, realizadas entrevistas e aplicados questionários. O estudo revelou que os processos de construção das identidades culturais da cidade de São Luís foram influenciados pela po

Amidação de Poli( metacrilato de metila)

Nesta dissertação foram avaliadas metodologias para reação de amidação de amostras comerciais de poli (metilmetacrilato), PMMA, com alilamina e benzilamina. A reação foi executada em tubo selado sob aquecimento a 90 C por sete dias, sem que nenhuma quantidade mensurável de amida pudesse ser detectada por FTIR e RMN. A reação foi reavaliada sob catalise de DBU, 3,4% molar, sem que nenhum resultado positivo obtido. O emprego de DBU associado ao NaCN como co-catalisador mostrou-se eficaz é o PMMA pode ser derivatizado em 30 %, com alilamina, e 13 % com benzilamina, sob as mesmas condições de temperatura e tempo. A analise elementar e o RMN-1H foram conclusivos na quantificação das reações enquanto o FTIR mostrou-se pouco eficaz devido a sobreposições de bandas. A taticidade das amostras comerciais de PMMA e do material produzido pode ser avaliada por RMN. Experimentos exploratórios efetuados em forno de microondas monomodo sob as mesmas relações molares com aquecimento a 120 C por 30 minutos com 80 W de potencia não foram capazes de promover alterações na matriz polimérica

Pedagogos que atuam como técnicos em assuntos educacionais na Universidade Federal do Rio de Janeiro

A presente dissertação de mestrado tem como objetivo a análise dos processos identitários dos pedagogos que atuam como técnicos em assuntos educacionais (TAEs) da Universidade Federal do Rio de Janeiro (UFRJ), as táticas construídas na ressignificação de seus fazeres profissionais, bem como as contribuições da formação acadêmica para que atuem nesse espaço de ensino. Foram tematizadas as seguintes questões: como se apresentam as teias que envolvem os processos identitários dos pedagogos que atuam na UFRJ como técnicos em assuntos educacionais? Quais as táticas construídas pelos técnicos em assuntos educacionais da UFRJ na ressignificação de seus fazeres profissionais como autores e sujeitos? Que contribuições o curso de formação acadêmica oferece na formação desses profissionais para que atuem nesse espaço de ensino? O referencial teórico da pesquisa fundamentouse nos conceitos de identidade e formação, por meio do estudo de autores como Hall, Vieira, Dubar, Nóvoa, Pineau, Josso e Bragança. A pesquisa apresenta abordagem qualitativa, desenvolvida especialmente pela escuta, transcrição e análise de entrevistas narrativas realizadas com quatro TAEs pedagogos da UFRJ que apresentam tempo de serviço diferenciado. Também foram utilizados questionários online distribuídos a todos os TAEs, pedagogos e licenciados, com um retorno de 58 questionários respondidos e analisados. A pesquisa apontou para a importância da formação e da autoformação, por trazerem novas perspectivas para a atuação do pedagogo. O processo identitário profissional dos TAEs/pedagogos foi apresentado, por meio das entrevistas e questionários, como movimento de construção, reconstrução e transformação, por meio das experiências. Concluímos também que as táticas consistem em possibilidades de esses profissionais modificarem e trabalharem com o imprevisto em seu cotidiano e agirem sobre as regras estabelecidas. Um aspecto importante é que o curso de Pedagogia contribui para a atuação desses profissionais na universidade, porém o mesmo curso não vislumbra outras atuações do pedagogo, direcionandoo, em sua maioria, para a docência dos primeiros anos do Ensino Fundamental. Assim, a pesquisa mostrou como as teias da vida vão tecendo o profissional TAE da UFRJ.

Gestão do conhecimento na EaD corporativa: tensões e possibilidades da transferência do conhecimento tácito nas comunidades e redes sociais

A partir da metade do século 20 o recurso meramente material deixou de ser considerado como a maior fonte de riqueza de uma instituição ou sociedade para ceder lugar à superestimação do ativo intelectual. Essa alternância de paradigma provocou no seio corporativo a preocupação de desenvolver estratégias e ferramentas gerenciais que fossem capazes de propiciar um meio oportuno para a geração e socialização do conhecimento organizacional. Na sociedade da nova economia, ancorada na valorização dos recursos intangíveis, o gerenciamento do conhecimento tácito, altamente pessoal e subjetivo, é concebido como importante tática para prover vantagem competitiva à empresa, inclusive àquelas que prestam serviços educacionais, concedendo lhe status de inovação apontada para o futuro. Uma das estratégias sugeridas pela literatura especializada reside na criação de redes de relacionamentos sociais que visem ampliar e potencializar a interação entre os partícipes no processo de compartilhamento de conhecimentos e troca de experiências para a apreensão da aprendizagem social colaborativa. Portanto, buscou-se examinar, nesta pesquisa, por intermédio de um estudo de caso particular, se uma importante e renomada instituição de ensino superior (IES) atuante no segmento de educação a distância online cumpre os fatores idiossincráticos e organizacionais relevantes para a transferência do conhecimento tácito, bem como se propicia aos docentes inseridos na comunidade virtual de professores (CVP) uma ambientação favorável para tal. O presente estudo sustenta-se em farto e consistente aparato bibliográfico sobre (i) conhecimento; (ii) gestão do conhecimento e (iii) redes, comunidades virtuais e novo social learning e objetiva confrontar as inflexões teóricas apresentadas com as análises realizadas quantitativa e qualitativamente dos dados coletados da unidade de amostra selecionada, na tentativa de prover elucidações capazes de satisfazer as hipóteses formuladas na pesquisa.

SEXUAL-BEHAVIOR OF TIBETAN MACAQUES AT MT EMEI, CHINA

Data on sexual behavior were collected in six groups of semi-commensal Macaca thibetana along the trail on the slope habitat between 1987 and 1989. Ignoring the common items such as mounting, presenting etc., 20 categories of sexual behavior were described. Most of the descriptions were likely to have enlarged the behavior repertoire reported in macaques, showing a great complexity of sociosexual interactions under the principally natural condition. A great diversity of grouping appeared in the mating season. The copulatory pattern was found to be the serial type contrary to previous speculation, and the mount-to-ejaculation ratio was higher in the central subgroup, as compared with the far-peripheral adult subgroup (FAS) with less male and female rivals. An age-class subdivision of sexually active males made it possible to show that the young adult male immigrants were the most active class in sexual activity. Subgrouping form FAS was a ''space-segregation'' tactic of mating for the losers of both sexes in the competition. Some parameters of copulation were also documented.
