Abstract Biases in adult sex ratios can alter the intensity of sexual selection by enhancing competition for mates. Under intense competition males increase their investment in behaviors to outcompete rivals (e.g., fighting). Yet, given that in male-biased environments mating opportunities are rare males may alternatively reduce costly courtship and/or adopt alternative reproductive tactics (ARTs). Males of the spider Pisaura mirabilis adopt different mating tactics, offering females genuine nuptial gifts (prey), nutritionally worthless gifts (prey leftovers), or no gifts. To test whether behavioral shifts between gift tactics are triggered by changes in the competitive environment, we established replicate spider populations under natural conditions at varying adult sex ratios (male-biased, female-biased and equal) and sampled gift tactics repeatedly over time. We additionally explored how male individual traits, such as body size and condition, affect the expression of ARTs. In male-biased populations males produced more gifts but of low quality, suggesting competition to trigger increased mating effort to ensure mate acquisition and fertilizations, but through a worthless gift tactic. Production of gifts and of genuine gifts was favored by high body condition, pointing to energetic limitations as being central for male reproductive capacity. We hence highlight two co-existing mechanisms at play to explain ARTs in this system, the competitive social environment where expression of gift tactics is based on optimal-decision making to overcome competition, and a conditional strategy linked to the individual’s energetic state.

In this article, for the first time, the distribution of well-known strategies and tactics of competitive actions by stages of the lifecycle according to the model of D. Miller and P. Friesen is carried out, which allows to provide a more accurate description of the competitive activity of an organization at different stages of its development. Tactics and strategy are closely related, and there is a need for their gradation in the context of the characteristics of the stages of the organization’s life cycle. This study is especially relevant in the period of the COVID-19 pandemic, where tactical models of competition play a special role in accordance with the selected strategies in the field of restaurant services. During the analysis of the activities of restaurant service establishments at different stages of the life cycle, certain patterns in the competitive actions of the organization were identified, which can be compared with the strategies and tactics of competition. The criteria for determining the stage of development of the organization, which determine the conduct of competitive processes, are given. Each stage of the organization’s life cycle is characterized: birth, development, maturity, flourishing, decline on the example of the restaurant services sector. It shows how organizations apply different strategies and tactics of competitive actions within each stage of the life cycle, as well as during the transition from one stage to another. The use of this article can help restaurant businesses by applying the developed matrix of tactical models of competition at various stages of the organization’s life cycle within the framework of a competitive strategy in the practical activities of the organization. Thus, the result of successful implementation of the strategy and tactical models is an increase in the number of potential guests, including permanent ones, and an increase in investment, production, sales and other opportunities.

Background and Study Aim. Tactics is one of the basic terms underlying the management of competitive activities of athletes. In freestyle wrestling, the participation tactics of athletes in the competition system is covered fragmentally and needs proper justification. The purpose of the study was to determine the features of the participation tactics of elite athletes in the competition system in freestyle wrestling during 2013-2016 Olympic cycle. Materials and Methods. This study analyzes the dynamics of performances and results of 24 elite freestyle wrestlers who won gold, silver and bronze medals at the Games of XXXI Olympiad 2016 in Rio de Janeiro in different weight categories (four athletes in each of six weight categories). To do this, we used athletes’ individual profiles on the United World Wrestling. Used an expert assessment devoted to the issues of tactics and tactical training. The experts (n = 8) were well educated (3 among them held Ph.D. diplomas) and experienced – 2 coaches of Ukrainian national team, and 1 athlete–national team’s member. On average, experts had almost 10 years of experience in training wrestlers of different ages. The results were processed using Microsoft Excel software. Results. The volume of competition practice of elite athletes during 2013-2016 changed in each season. In the 2013 season, the average group number of competitions in which athletes participated was 3.84 ± 2.06, in 2014 – 3.50 ± 1.79. In the 2015 season, those indicators were the highest – 4.17 ± 1.87, but in 2016 they decreased to 3.71 ± 1.52. The participation tactics in the competition system in freestyle wrestling during the season and the four-year cycle differed depending on the dynamics of sports results. Four types of tactics used by the elite athletes in freestyle wrestling in 2013-2016 were identified: leadership holding, gradual improving of results, combined, leadership returning. It was found that during 2013-2016, most athletes (58.33-79.17%) used a variety of tactics that involved performances in one Olympic weight category. In 2014 and 2015, some athletes (20.83 and 25.00%, respectively) used different options in other weight categories, choosing one of them as a priority and one or two – as additional. Conclusions. There are four types of participation tactics in the competition system in freestyle wrestling. In 2013-2016 Olympic cycle they included leadership holding, gradual increase of results, combined, leadership return. The main differences between types of tactics are the volume of competition practice, the dynamics of results, the choice of weight category. The most relevant was the type of tactics with performances exclusively in the Olympic weight category during four seasons.

In species with alternative reproductive tactics, males that sneak copulations often have larger, higher quality ejaculates relative to males that defend females or nest sites. Ejaculate traits can, however, exhibit substantial phenotypic plasticity depending on a male's mating role in sperm competition, which may depend on the tactic of his competitor. We tested whether exposure to males of different tactics affected sperm number and quality in the swordtail Xipophorus nigrensis , a species with small males that sneak copulations and large males that court females. Sperm swimming speed was higher when the perceived competitor was small than when the competitor was large. Plasticity, however, was only exhibited by small males. Sperm number and viability were invariant between social environments. Our results suggest sperm quality is role-dependent and that plastic responses to the social environment can differ between male reproductive tactics.

In martial arts, data mining technologies are used to describe and analyze the moves of athletes and changes in the process and sequences. Martial arts is a process in which athletes use all kinds of strengths and actions to make offensive and defensive changes according to the tactics of opponents. One such martial arts is Wushu arts as it has a long history in reference to Chinese martial arts. During the Wushu competition, Wushu athletes show their adaptability and technical level in complex, random, and nonlinear competitive abilities, organized and systematic skills, tactics, and position movement. Using data mining techniques, in-depth mining a particular type of martial arts competition technology and tactics behind statistical data, and using the data to find the law of change to solve some problems, for martial arts athletes in daily training to develop technology and tactics and improve competition results, is the practical significance of data mining in martial arts athletes competition. This research explored the relationship between goal-oriented and mental intensity and their effect on competitive success outcomes.

With the rapidly developing of the scientific research in the field of sports, big data analytics and information science are used to carry out technical and tactical statistical analysis of competition or training videos. The table tennis is a skill oriented sport. The technique and tactics in table tennis are the core factors to win the game. With the endlessly emerging innovative playing techniques and tactics, the players have their own competition styles. According to the competition events among athletes, the athletes’ competition relationship network is constructed and the players’ ranking is established. The ranking can be used to help table tennis players improve daily training and understand their ability. In this paper, the table tennis players’ ranking is established their competition videos and their prestige scores in the table tennis players’ competition relationship network.

There has been much debate about how male alternative reproductive tactics (ARTs) evolve. In particular, researchers question whether ARTs have evolved as a conditional, ‘best of a bad job’ strategy where one tactic has higher fitness than the other, or whether they have evolved as a result of a genetic polymorphism where both tactics have equal fitness. Despite the large number of species known to have ARTs, tests of equal fitness between tactics have only been conducted in a handful of species. We tested the prediction of equal fitness using the plainfin midshipman (Porichthys notatus), a species with two well characterized male ARTs: guarding type I males and cuckolding type II males. We collected data across three years and three sampling locations to determine the proportion of each reproductive tactic, as well as the proportion of offspring sired by each male type using microsatellite markers. Our analysis suggests that males adopting the conventional guarding tactic likely have higher fitness compared to males adopting the cuckolder type II tactic. Also, we show that the guarding male tactic is able to gain paternity through cuckoldry, and that these males, who sometimes guard and sometimes cuckold, are responsible for the majority of paternity lost within nests. Indeed, the classic cuckolding type II males were responsible for only a small fraction of the paternity lost. These results highlight the degree of flexibility in male behaviour even among individuals adopting the same male tactic. Taken together, our results provide the first exploration of the evolution of male ARTs in plainfin midshipman and, given the tractability of midshipman system, a valuable next step will be to look for gene-by-environment interactions on tactic development and expression.

Abstract Species with intense male–male competition for access to females often show alternative reproductive tactics (ARTs) where males of lower competitive ability adopt a sneaky behavior to gain access to mates. These ARTs are usually associated with intrasexual dimorphisms, in that males with distinct morphologies show different tactics. In some cases, however, males adopt different tactics without being dimorphic. Male Drosophila prolongata exhibit continuous variation in body size and shape, with enlarged forelegs that they use in male-male contests and in courtship, including stimulation of the female’s abdomen. During this “leg vibration,” however, nearby males can intercept the courted female and mate without their own courtship. Here, we studied the causes and consequences of these different mating tactics in competitive mating trials between males varying in their size and shape. We found that male mating tactics were condition-dependent. Whereas large, high-condition males were more likely to show leg vibration in their courtship, smaller, lower-condition males were more likely to intercept. However, the number of offspring produced was independent of male condition and reproductive tactic. We discuss possible scenarios for the evolution and maintenance of the ARTs and some future directions for the study of ARTs in this species and in general.

Over the last decades, battles for technological dominance between competing technologies have had a significant impact on many industries. In this paper, we investigate how the fast-moving technology environment influences the tactical choices of companies trying to establish their products as de facto standards. We analyze contextual changes in the evolution of standards wars using a literature survey supported by three integrated case studies. We develop the portfolio of tactics that competing companies should apply in the management of emerging standards wars, composed both of traditional and new deployment tactics. We demonstrate that contextual and tactical changes heighten the pressures on timing and the competition exposure in today's standards competitions. As a consequence, it becomes more difficult for an alleged "winner" to "take all" in the marketplace.

AbstractThis paper extends research on nonprofit advocacy by exploring the relationship between competition, nonprofit mission, and policy advocacy. Previous research indicates that charitable nonprofits serving specialized populations, such as immigrants or veterans, often engage in policy advocacy. This could benefit marginalized populations whose interests are articulated by nonprofit organizations. However, population ecology theory in organizational sociology predicts that generalist organizations will outperform specialists in uncertain environments. At the very times when nonprofits serving specialized constituencies should focus on advocacy the most – for example to protect funding in competitive policy environments – they may be least able to do so. Drawing on survey data from charitable nonprofits in Boston, Massachusetts, we find that competition and specialization have direct positive effects on nonprofit engagement in advocacy and the use of formal and grassroots tactics. However, the effect of competition is weakened by nonprofit specialization. Nonprofit specialists that report higher competition for resources are less likely to participate in policy advocacy and use fewer formal and grassroots tactics. Specialists that report higher service delivery competition use fewer formal advocacy tactics. These findings suggest that we should be cautious in looking to the nonprofit sector, particularly organizations serving specialized populations, to provide constituent representation through policy advocacy in competitive environments.

Bitterling are a group of freshwater fishes that lay their eggs on the gills of living freshwater mussels, using the mussel as a protective environment for embryo development and utilising the mussels own respiration to ensure fertilisation. This unusual spawning mechanism, using a spawning site that can be easily manipulated, makes bitterling ideal of reinvestigating sperm competition and making system evolution. Here, using a range of bitterling species, a series of aquarium experiments were conducted, as well as morphological and histological studies of the sperm and testes. It was shown that males were highly sensitive to sperm competition, ejaculating at a higher frequency and subsequently becoming more sperm depleted where sperm competition was high. There were few differences between mating tactics except in relative testis size, where larger males had proportionally larger reproductive apparatus, but ejaculates were of a similar size. The timing of ejaculates was found to be crucial, with a peak in sperm concentration within the mussel mantle cavity 30 seconds after ejaculation. The spatial clustering of fertilisation opportunities and OSR were found to affect ejaculate frequency, ejaculate distribution among mussels, the dominance of gender males and subsequently the opportunity of subordinate males to sneak fertilisations. Significant differences in the spermatogenic strategy and the structure of the reproductive apparatus among species were identified, as well as significant differences between species in the morphology of spermatozoa.

Bullying is ubiquitous and a major cause of psychological distress and disease. While most bullying research investigating the predisposing, precipitating and perpetuating factors has focused on victims, important gaps remain regarding the theoretical drivers of bullying perpetration. Using sexual selection and intrasexual competition as a theoretical framework, researchers have argued that bullying is an evolved behaviour that enables bullies to obtain or maintain a strong position in the social hierarchy and have greater access to resources, including sexual and romantic experiences. Intrasexual competition comprises two key features: competitor derogation and self-promotion. Bullying could be considered as a type of repeated competitor derogation, but the extent to which bullies engage in self-promotion tactics is unknown. As body shape and size are of central importance to males and females in the context of intrasexual competition, the aims of this thesis were: to determine whether body weight or body image independently or jointly predict bullying role; and to examine the extent to which bullies, victims and bully-victims are preoccupied with self-promotion through body alteration, and whether this is related to psychological functioning. A large school-based study (The Bullying, Appearance, Social Information Processing and Emotions Study; The BASE study) of adolescents in the UK was conducted. Study 1 investigated whether body weight or body image (i.e., actual or perceived underweight or overweight) was independently associated with bullying role (bully, victim or bully-victim), and whether body weight and body image interacted to predict bullying role amongst adolescent boys and girls. Study 2 examined whether bullies, victims and bully-victims were at increased risk of weight loss preoccupation compared to adolescents uninvolved in bullying, whether psychological functioning mediated the relationship between bullying role and weight loss preoccupation, and whether sex was a key moderator. Study 3 examined whether bullies, victims and bully-victims had a higher desire for cosmetic surgery compared to adolescents uninvolved in bullying, whether the relationship between bullying role and desire for cosmetic surgery was direct or mediated by psychological functioning, and whether any effects were sex-specific. The findings offer several new contributions to knowledge. Firstly, it was revealed that body image, rather than actual body weight, is associated with being a victim and bully-victim. Bullies were of average weight and were more likely to be at an advanced pubertal status (girls only). Secondly, being a male or female bully was directly associated with increased desire for cosmetic surgery and weight loss preoccupation (boys only). The relationship between being victimised (as a victim or bully-victim) and cosmetic surgery desire and weight loss preoccupation was mostly mediated by reduced psychological functioning. Overall, victims had the highest desire for cosmetic surgery, whilst bully-victims had the highest weight loss preoccupation; there were no significant differences between male and female victims or bully-victims. In conclusion, the findings that male and female adolescent bullies are engaging in or cognizing about self-promotion strategies to improve physical appearance, which was unrelated to psychological functioning, are consistent with the theory of bullying as a form of intrasexual competition. Bullies are thus multi-strategic in their attempt to obtain or maintain social dominance. Bullied adolescents are similarly concerned about their appearance, but this is mostly because of reduced self-esteem, body-esteem and emotional problems as a result of being bullied. Thus, adolescents involved in bullying are at increased likelihood of attempting to alter their physical appearance, albeit via different pathways and with likely different outcomes. The research advances theoretical understanding about bullies and has practical implications for understanding the body concerns and self-promotion tactics of bullies, victims and bully-victims.

O processo de seleção sexual influencia de forma intensa o sucesso reprodutivo de cada indivíduo. Desde sua formulação teórica durante o século XIX, evidências cumulativas a respeito da poliandria em fêmeas permitiram a ampliação de seu conceito inicial, uma vez constatada que a disputa pela paternidade da prole não se limitava à competição pelo acesso à fêmea, mas poderia também prolongar-se mesmo após a cópula. Durante a década de 1970, essa disputa pós-copulatória entre machos foi formalizada sob o conceito de competição espermática, a qual visa a maximizar o sucesso do esperma de um macho sobre um rival na fertilização dos ovos. Evidências para um número crescente de táxons demonstram que a intensa competição pré e pós-copulatória entre machos é também uma das fontes responsáveis pela evolução e manutenção de táticas alternativas de reprodução dentro de uma mesma espécie, nas quais machos com menor sucesso na monopolização de fêmeas e combate com intraespecíficos adotam comportamentos furtivos para acesso ao sexo oposto, como forma de assegurar algum sucesso reprodutivo. Em muitas espécies, a adoção de táticas alternativas de reprodução são relacionadas não somente às diferenças comportamentais entre os machos, mas também à diversidade fenotípica dentro do mesmo sexo, caracterizada por descontinuidades morfológicas, fisiológicas e de ciclo de vida, conhecida pelo termo ‘dimorfismo intrassexual’. Em lulas da família Loliginidae, a existência de morfos alternativos, denominados machos consort e sneaker, já foi constatada para diversas espécies e é associada a diferenças comportamentais entre eles, principalmente relacionadas à posição de cópula e sítio de deposição de espermatóforos no interior da fêmea. No entanto, a associação entre táticas alternativas de reprodução e dimorfismo intrassexual em machos é praticamente desconhecida, com exceção à espécie Heterololigo bleekeri, para a qual esse dimorfismo tem sido estudado extensivamente ao longo da última década. Nesse contexto, a presente Dissertação de Mestrado teve como principal objetivo investigar a existência de dimorfismo intrassexual masculino em Doryteuthis plei (Blainville, 1823), uma espécie de importância comercial para as regiões Sul e Sudeste do Brasil e para a qual, apesar de evidências indiretas sugerirem sua presença, tal dimorfismo nunca havia sido averiguado. Por meio de análises morfológicas e modelos estatísticos, o primeiro capítulo descreve a existência desse dimorfismo na espécie, o qual foi reconhecido a partir da constatação da presença de duas classes de tamanho de machos sexualmente maduros, caracterizadas pela produção de espermatóforos e espermatângios com morfologias descontínuas. Além disso, espermatângios amostrados de machos das duas classes de tamanho mostraram-se congruentes àquelas implantados nos dois sítios distintos da fêmea, resultado que permitiu associar o dimorfismo intrassexual à adoção das táticas de sneaker e consort na espécie. A partir dessa constatação, o primeiro capítulo explorou ainda o investimento gonadal exibido por machos dimórficos. Os resultados mostraram que machos sneakers apresentavam maiores investimentos relativos em gônadas do que machos consorts, um resultado que se enquadra nos modelos teóricos de “sneaks and guarders” de competição espermática. No entanto, enquanto as premissas teóricas propõem também que machos sneakers devem apresentar maiores investimentos por fêmea, constatamos que, na espécie de estudo, machos sneakers produzem espermatóforos com menor proporção de massa espermática do que machos consorts. Esses resultados, somados a observações comportamentais realizadas ao longo desse trabalho, sugerem que a estratégia adotada por machos sneakers deve estar relacionada ao fracionamento de seu investimento em produtos ejaculatórios, de forma que investimentos menores por fêmea permitiriam a realização de maior número de cópulas. Dando continuidade à caracterização do dimorfismo intrassexual na espécie, análises comparativas entre machos dimórficos com relação a estruturas do sistema reprodutor, tema do segundo capítulo, demonstraram que as diferenças quanto à morfologia funcional de espermatóforos intactos estavam associadas às divergências encontradas quanto à reação espermatofórica, liberação de espermatozoides e morfologia de espermatângios entre machos sneakers e consorts. Além disso, sob o contexto da competição espermática, o segundo capítulo discute como o padrão de reprodução de lulas da família Loliginidae, e.g., a existência de dois sítios de fertilização e diferenças nos intervalos entre cópulas e desovas, resultaria em pressões seletivas divergentes sobre os produtos ejaculatórios de machos dimórficos e influenciaria a evolução e manutenção do dimorfismo intrassexual na espécie. Por fim, o terceiro capítulo aborda a descoberta de machos com espermatóforos e espermatângios com morfologias intermediárias entre os fenótipos de sneakers e consorts, além da questão da diferença de idade entre machos dimórficos. Combinados, os resultados desse capítulo permitiram a proposição de uma hipótese ontogenética sobre a expressão de fenótipos alternativos na espécie, uma questão extremamente inovadora para cefalópodes. Apesar de tratar-se de um campo ainda completamente inexplorado para o grupo, espera-se que esses resultados contribuam para a compreensão dos fatores responsáveis pela expressão sequencial de fenótipos alternativos e pela determinação do dimorfismo intrassexual em lulas
Sexual selection comprises a powerful force that intensively influences the reproductive success of each individual. Since its theoretical formulation in the nineteenth century, cumulative evidence regarding the existence of polyandry in females has expanded its initial concept, once it became clear that offspring paternity disputes were not limited to the competition for female access, but that they could in fact be prolonged even after copulation. In the 1970s, this male post-copulatory dispute was formalized under the concept of sperm competition, which aims at maximizing the success of one male’s sperm over its competitors in the fertilization of females’ eggs. Evidence gathered from a growing number of taxa has shown that intense pre and post-copulatory competition between males is also one of the responsible sources for the evolution and maintenance of alternative reproductive tactics within a species, in which males that are less successful in mate guarding and fighting contests with conspecifics adopt sneaking and opportunistic behaviors as a way to ensure some mating success. In many species, alternative mating tactics are not restricted to behavioral differences between males, being also related to a phenotypic diversity, with discontinuous morphological and physiological traits and distinct life histories between conspecifics, a phenomenon known as intrasexual dimorphism. In loliginid squids, the existence of alternative morphs (sneaker and consort males) has already been reported for several species, and it is has been correlated to behavioral differences, specially related to mating position and spermatophore deposition sites within the female\'s body. However, the association between alternative mating tactics and male intrasexual dimorphism is virtually unexplored, except for the species Heterololigo bleekeri, in which such dimorphism has been extensively studied over the last decade. In this context, the present Master’s Dissertation aimed to investigate the existence of male intrasexual dimorphism in Doryteuthis plei (Blainville, 1823), a squid of commercial importance in southern and southeastern Brazil, and for which such dimorphism has never been investigated, although indirect evidence suggests its existence. Using morphological analyses and statistical models, the first chapter describes the presence of such dimorphism in the species, which was detected based on the identification of two body size classes of sexually mature males, characterized by spermatophores and spermatangia displaying discontinuous morphologies between each other. Moreover, spermatangia sampled from both body size classes were congruent with those implanted on distinct female sites, a result that allowed the association between intrassexual dimorphism and adoption of sneaker and consort mating tactics in the species. Additionally, the first chapter also investigated the gonadal investment from dimorphic males, showing that sneakers exhibited higher investments in gonads than consorts, a result that fits into the theoretical ‘sneaks and guards’ models of sperm competition. However, while theoretical assumptions propose that sneakers should also present larger investments per female, we show that D. plei sneaker males produce spermatophores with lower concentrations of sperm mass than consorts. Combining these results with behavioral observations obtained throughout this study, we suggest that the sneaker strategy might be related to partitioning their ejaculate expenditure into extra mating opportunities, thus investing less per female but more in number of copulations. A further characterization of intrasexual dimorphism in this species was the main subject of the second chapter. Through comparative analyses of reproductive structures from dimorphic males, the results revealed that differences in the structural morphology of intact spermatophores were associated to differences regarding the spermatophoric reaction, spermatozoa release and spermatangia morphology between sneakers and consorts. Furthermore, under the context of sperm competition, the second chapter also provided a discussion on how the reproductive pattern of loliginid squids, e.g., the existence of two sites for fertilization of eggs and differences in the interval between mating and egg-laying, might result in divergent selective pressures on ejaculates from dimorphic males, influencing the evolution and maintenance of intrasexual dimorphism in this species. Finally, the third chapter describes the discovery of males that produced spermatophores and spermatangia displaying intermediate morphologies between both sneaker and consort phenotypes, and age differences reported for dimorphic males in the species. Combined, these results allowed the formulation of an ontogenetic hypothesis regarding alternative phenotype expression, which is extremely innovative for cephalopods. Although this hypothesis comprises a completely unexplored field for this group, it is highly expected that these results might contribute to the further understanding of possible factors that may be responsible for the sequential expression of alternative phenotypes, and ultimately for the determination of intrasexual dimorphism in squids

Розвинено категорійно-понятійний апарат теорії конкуренції, конкурентних стратегій, а також запропоновано концептуальний підхід до формування конкурентної стратегії на основі безперервної інноваційної моделі. Розглянуто і критично проаналізовано еволюціонування теорії конкуренції в перебігу формування економічних систем та доведено, що Індустрія 4.0 докорінно трансформує основні важелі конкурентного середовища, соціальний базис конкурентних стратегій та інструментів суперництва, основаних на інтелектуальній компоненті. Таке бачення уможливлює імплементування основних елементів Індустрії 4.0 в діяльність торговельних українських підприємств, зважаючи на їх роль у ланцюгу створення цінності. Визначено особливості функціонування механізму формування динамічного конкурентного потенціалу, який забезпечує швидкість реагування на зміни ринкової ситуації, стратегічну гнучкість та готовність підприємства до змін. На основі систематизації наукових підходів до формування конкурентної стратегії запропоновано її безперервну інноваційну модель, рушійним механізмом якої мають стати стратегічні дії підприємства щодо вдосконалення бази знань, а отже формування стійких та динамічних конкурентних переваг. До їх числа віднесено: мотиваційні механізми конкурування; системи управління знаннями й продукування генерації ідей та інновацій; інструменти маркетингу, сценарії досягнення лідерства; забезпечення інтересів стейкголдерів; партнерські стратегії. Удосконалено науково-методичний підхід щодо формування концептуального паттерну стратегічного конкурентного потенціалу підприємства роздрібної торгівлі, який на відміну від інших розробок включає: можливості, що склалися у зовнішньому середовищі; споживчий потенціал; потенціал внутрішнього середовища підприємства, і спрямований на підвищення конкурентного потенціалу підприємства. Концептуальний паттерн формування стратегічного конкурентного потенціалу, здатний не тільки формувати й підтримувати конкурентні переваги, але й продукувати інновацію цінностей для забезпечення безперервності розвитку торговельного підприємства. Виокремлено та обґрунтовано забезпечуючий ланцюг системних цінностей, який продукується функціональними підсистемами торговельного підприємства та формує унікальну торговельну пропозицію. Пропонований підхід забезпечить сучасне підґрунтя для формування конкурентної стратегії торговельного підприємства. Ідентифіковано та проведено класифікацію факторів впливу на формування конкурентних стратегій та культуру безперервного інноваційного бізнес-моделювання, яка, на відміну від усталених, виокремлює екзогенні (глобалізаційні процеси, межі ринків, темпи розвитку технологій, невизначеність середовища); ендогенні (динаміка та розмір внутрішнього потенціалу підприємств торгівлі, організаційні знання та навики, рівень між фірмової невизначеності) та стратегічні дії підприємств щодо вдосконалення бази знань та забезпечення безперервності розвитку конкурентної стратегії (партнерські стратегії, сценарії досягнення лідерства, забезпечення інтересів стейкголдерів, співконкуренція, внутрішні інноваційні процеси). Такий підхід дозволяє підприємствам торгівлі при формування конкурентної стратегії базуватися на безперервній інноваційній моделі. Дістала подальшого розвитку теоретизація понятійного апарату конкурентної стратегії підприємства, а саме: визначено сутність поняття «конкурентна стратегія», яка, на відміну від усталених поглядів, розглядається як динамічна модель поведінки підприємства, спрямована на досягнення сталої конкурентоспроможності в межах місії, націленої на задоволення потреб споживачів та забезпечення економічних, масштабних та іміджевих ефектів підприємства. Розвинено трактування сутності поняття «інновація цінності», яку на відміну від інших, запропоновано визначати як стратегію, що забезпечує здатність системи продукувати ринкові зміни на основі збалансованого поєднання виключної корисності, цільової собівартості, стратегічного ціноутворення задля безперервного розвитку підприємства у конкурентному середовищі. На підставі моніторингу ринку канцтоварів України удосконалено науково-методичний підхід до якісного оцінювання ситуації на ринку, який на відміну від інших розробок, ґрунтується на визначенні системи інтегрованих оцінок зовнішнього конкурентного макропотенціалу, в розрізі визначальних екзогенних факторів і залежить від їх варіації та рівня впливу на діяльність підприємства, що дозволило оцінити зовнішній конкурентний потенціал, який впливає на формування конкурентної стратегії підприємств роздрібної торгівлі. Сформовано теоретико-методичний підхід до визначення ефективності управління конкурентною позицією торговельного підприємства, що базується на інтегрованій оцінці масштабу конкурентного потенціалу, сили конкурентного впливу та результативності стратегічних дій конкурентів, та спрямований на трансформування стратегічного бачення позиції підприємства на ринку як конкурентної стратегії, а стійкість конкурентних переваг дозволяє визначати в контексті можливості утримання конкурентної позиції у довгостроковій перспективі. Запропоновано комплексний інтегральний показник ефективності управління конкурентною позицією підприємств роздрібної торгівлі на основі результативності стратегічних дій та сили конкурентного впливу. Все це формує аналітичну складову розробки конкурентної стратегії, яка забезпечить механізм порівняння динамічності, гнучкості конкурентних переваг, для формування сталої конкурентоспроможності в межах корпоративної стратегії спрямованої на задоволення потреб споживачів та забезпечення економічних, масштабних та іміджевих ефектів підприємства торгівлі. Набув подальшого розвитку ресурсний підхід до оцінювання внутрішнього конкурентного потенціалу підприємств роздрібної торгівлі, в основу якого, на відміну від інших, покладено розрахунок інтегрального показника на основі збалансованої системи часткових показників за такими складовими потенціалу, як: споживчий, фінансовий, клієнтський, бізнес-процесів, стратегічний та потенціал розвитку, що дає можливість комплексно визначити рушійні сили конкурентного потенціалу, розглянути синестезію пріоритетних конкурентних складових підприємства роздрібної торгівлі з цілями його корпоративної стратегії та забезпечити порівняння між існуючим станом та прогнозним рівнем конкурентного потенціалу підприємства. Запропоновано системно-раціональний підхід до реалізації тактичного конкурентного позиціювання в напрямку активних стратегічних дій підприємства роздрібної торгівлі в межах загальної конкурентної стратегії комбінування. Даний підхід ґрунтувався на припущенні, що формування мережі магазинів одного підприємства має відбуватися на основі експоненціального приросту корисності, ефекту масштабу, накопиченого досвіду й знань, зростанням довіри з боку зацікавлених осіб. Даний підхід складається з методики перевірки наявності тісноти синергійних зв’язків між магазинами, що входять до складу одного підприємства та моделі визначення раціонального масштабу мережі магазинів, побудованої на основі показника відносного загального доходу, який продукується мережею магазинів.

The dissertation is devoted to substantiation of theoretical and methodical bases and development of practical recommendations on construction of competitive strategy of commercial enterprise which is directed on formation of dynamic competitive advantages in the process of maintenance of sustainable development of the enterprise. It is developed categorical and conceptual system of theory of competition, competitive strategies, and also it is proposed a conceptual approach to the formation of a competitive strategy based on a continuous innovation model. It is considered and critically analyzed the evolution of competition theory during the formation of economic systems and it is proved that Industry 4.0 radically transforms the main levers of the competitive environment, the social basis of competitive strategies and rivalry tools based on the intellectual component. Such vision enables the implementation of the main elements of Industry 4.0 in the activities of Ukrainian commercial enterprises, considering to their role in the chain of creation the value. It is defined the peculiarities of functioning of the mechanism of formation of dynamic competitive potential which provides speed of reaction to changes of market situation, strategic flexibility and readiness of the enterprise to changes. Based on the systematization of scientific approaches to the formation of competitive strategy it is proposed its continuous innovative model, the driving mechanism of which should be the strategic actions of the enterprise to improve the base of knowledge, and therefore the formation of sustainable and dynamic competitive advantages. These include: motivational mechanisms of competition; knowledge management systems and production of idea generation and innovation; marketing tools, scenarios of achieving the leadership; ensuring the interests of stakeholders; partnership strategies. It is improved the scientific and methodological approach to the formation of the conceptual pattern of strategic competitive potential of the retail enterprise, which, unlike other developments, includes: opportunities that have developed in the external environment; consumer potential; the potential of the internal environment of the enterprise, and aims to increase the competitive potential of the enterprise. Conceptual pattern of formation of strategic competitive potential is able not only to form and maintain competitive advantages, but also to produce innovation of values to ensure the continuity of development of commercial enterprise. It is highlighted and grounded the providing chain of system values, which is produced by the functional subsystems of trade enterprise and forms a unique trade offer. The suggested approach will provide a modern basis for formation of competitive strategy of commercial enterprise. It is identified and carried out the classification of impact factors on the formation of competitive strategies and culture of continuous innovative business modeling, which, unlike established, carves out exogenous (globalization processes, markets borders, the rate of technology development, the uncertainty of the environment); endogenous (dynamics and size of internal potential of trade enterprises, organizational knowledge and skills, the level interfirm uncertainty) and strategic actions of enterprises to improve the knowledge base and ensure the continuity of competitive strategy (partnership strategies, scenarios of achieving the leadership, ensuring the interests of stakeholders, co-competition, internal innovation processes ). Such approach allows the trade enterprises during the formation of competitive strategy to base on continuous innovation model. Received of further development of theorizing conceptual system of competitive strategy of the enterprise, namely: it is defined he essence of the concept of «competitive strategy», which, unlike established views, is considered as a dynamic model of enterprise behavior aimed at achieving sustainable competitiveness within the mission aimed at meeting consumer needs and ensuring economic, large-scale and image effects of the enterprise. It is developed interpretation of the essence of the concept of «value innovation», which, unlike others, is proposed to define as a strategy that ensures the ability of the system to produce market changes based on the balanced combination of exceptional utility, target prime cost, strategic pricing for continuous development in the competitive environment. Based on the monitoring of the stationery market of Ukraine, it is improved the scientific and methodological approach to qualitative assessment of the market situation, which, unlike other developings, is based on the definition of the system of integrated assessment of external competitive macro-potential, in terms of determinative exogenous factors and depends on their variation and the level of impact on the enterprise activity, which is allowed to assess external competitive potential that effects on the formation of competitive strategy of the retail trade enterprises. It is formed theoretical and methodical approach of determination of management efficiency of competitive position of commercial enterprise, which is based on the integrated assessment of the scale of competitive potential, strength of the competitive impact and effectiveness of strategic actions of competitors, and aims at transforming of strategic vision of the position of the enterprise on the market as a competitive strategy, and the stability of competitive advantages allows to determine in the context of the possibility of maintaining a competitive position in the long prospect. It is suggested a complex integrated indicator of the effectiveness of managing the competitive position of the retail trade enterprises based on the effectiveness of strategic actions and the strength of competitive influence. All it forms an analytical component of the development of competitive strategy, which will provide a mechanism of comparing the dynamism, flexibility of competitive advantages, to form a sustainable competitiveness within the corporate strategy aimed at meeting consumer needs and ensuring economic, scale and image-building effects of trade enterprise. It is acquired further resource approach to assessing the internal competitive potential of the retail trade enterprises, on the basis, unlike others, is laid the calculation of integrated indicator based on a balanced system of partial indicators for such components of potential as consumer, financial, customer, business processes, strategic and development potential, which allows to determine comprehensively the driving forces of competitive potential, to consider the synesthesia of priority competitive components of the retail trade enterprise with the goals of its corporate strategy and to provide a comparison between the existing state and the forecast level of competitive potential. It is suggested system-rational approach to realization of tactical competitive positioning in the direction of active strategic actions of the retail trade enterprise within general competitive strategy of combination. This approach was based on the assumption that the formation of chain store system of one enterprise should be based on the exponential increase of utility, effect of scale, accumulated experience and knowledge, increasing trust from interested person. This approach consists of a method of checking the closeness of synergies between stores that are part of the same enterprise and the model of determining the rational scale of the chain store system, built on the basis of the relative total revenue, which is produced by the chain store system. It is improved scientific and methodological approach to the formation of a competitive strategy of the retail trade enterprise of stationery, which consisits of combination of sequences of actions of intuitive reasoning scenarios of achieving the leadership at the market and, in contrast with the existing developings, takes into account the structuring of tactical competitive position, identifying alternative tactical tasks tactical which forms tactical competitive advantages and competitive tactics with subsequent iteration of the convergence of the probable and desired state of the system in terms of resource and time constraints. The results of the received researches and practical decision of issues to form the competitive strategy were reflected in practical activity of the enterprises of retail trade enterprises of stationery of Vinnytsia and Khmelnytskyi Chamber of Commerce and Industry.

Essa dissertação apresenta dois objetivos de trabalho (1) desenvolvimento e avaliação um programa computacional para análises técnico-táticas em combates de judô; (2) analisar as ações técnico-táticas utilizadas por atletas de judô de quatro classes de idade (pré-juvenil, juvenil, júnior e sênior), nas oito categorias de peso oficiais do Brasil (super-ligeiro até pesado) no sexo masculino e feminino, em dois níveis diferentes, a saber: (a) Circuito Paulistano e (b) Estadual de São Paulo. Nesta segunda parte, foram analisadas as variáveis: i) estrutura temporal do combate; ii) execução e orientação de golpes; iii) quantificação de pontuação; e iv) caracterização do tipo de pegada. Para verificação da objetividade do programa computacional, três experts realizaram 20 análises de combate, sendo que um deles analisou as mesmas 20 por três vezes (1° expert, n= 20; 2° expert n= 20, e; 3° expert n= 60). Para a comparação entre grupos observados no segundo estudo e para verificar a correlação de concordância (CCC) entre as medidas dos experts, utilizou-se a Análise de Variância e, quando necessário, post hoc de Tukey, com nível de significância adotado de 5%. Os resultados quanto ao programa demonstraram forte correlação intra e inter-expert, com alto grau de concordância (> 0,90 de índice) para 41 grupos de variáveis e (>0,80 de índice) para 37 grupos de variáveis, respectivamente. Para o segundo estudo, os principais resultados para o sexo masculino foram: no nível estadual e/ou a classe sênior, utilizam maiores tempos de combate, de luta em pé (tachi-waza) de movimentação livre, de pegada e da variação de pegada e direção de ataque. Nos grupos do sexo feminino, ocorreram diferenças entre o nível estadual e/ou a classe sênior (exceto quando comparado à classe pré-juvenil no tempo de combate sem pausa e no tempo de pegada) e os demais grupos - com tempos maiores para combate, tachi-waza, movimentação livre e pegada -, demonstraram diferenças entre a categoria pesado - que possuiu tempos de combate, tachi-waza, movimentação livre e pegada menores do que as categorias meio-leve, leve e meio-médio. Quanto às diferenças entre níveis, as atletas do estadual apresentaram uma frequência maior de entradas de golpe e de quantidade de tipos de pegada utilizados
This dissertation has two goals: developing and evaluating a computer program for the analysis of technical and tactical combat in judo, and analyzing technical-tactical actions used by judo athletes from four age classes (pre-juvenile, juvenile, junior and senior) in the eight official Brazilian weight categories (super-light to heavy), males and female, at two different levels, namely: (1) São Paulo City (Paulistano) and (2) São Paulo State levels. The variables were: i) temporal fight structure, ii) execution and direction of throws, iii) quantification of scores and iv) characterization of grip type. In order to verify the objectivity of the computer program, three experts conducted 20 analyses of combats, with one expert examining three times the same 20 (1st. expert, n = 20; 2nd. expert n = 20; 3rd. expert n = 60). For comparison between groups observed in the second study and in order to verify the concordance correlation (CCC) between experts measurements, analysis of variance and, when necessary, post hoc Tukey test with significance level p <0.05, were used. The results from the software showed strong intra and inter-expert agreement, with higher rate (> 0,90 of index) in 41 groups of variables and (>0,80 of index) in 37 groups of variables, respectively. For the second study, the most significant results from the male group were at the state and/or the senior class, using longer periods of combat, standing fight (tachi-waza), free displacement, grip time and variation in grip type, and direction of attacks. In females, there were differences between state and/or the senior class (except when compared to pre-juvenile in fight time without pause and grip time) and other groups, with more combat time, tachi-waza, free displacement and grip - showing differences between the heavyweight, who presented less combat, tachi-waza, free movement and grip times, and half-lightweight, lightweight and welterweight categories. Regarding differences between levels, state-level athletes used a higher frequency of techniques and different grip types

The availability of reproductive sites is a major factor shaping the behavior of males and females in species with resource-based mating systems. Using a meta-analytic approach, we tested five predictions directly or indirectly derived from the mating system theory. We expected that reproductive site limitation would lead to: (1) intense male-male competition for resource possession; (2) high variance in male reproductive success, generating high values of opportunity for sexual selection; (3) high intensity of selection on male traits related to resource possession; (4) high sperm competition risk; and (5) low quality of paternal care. We compiled information from observational and experimental studies that compared the reproductive behavior of individuals of the same species under low and high reproductive site limitation. We found that, when reproductive sites are limited, there is a slight increase in male-male competition, with higher rates of nest takeover and agonistic interactions, and a slight increase in the selection gradient on male traits, with successful males tending to be larger than unsuccessful males. Reproductive site limitation has no consistent effect on the opportunity for sexual selection and on the sperm competition risk. However, territorial males invest more in gonads and lose less paternity when reproductive sites are limited. There is also no clear effect of reproductive site limitation on the quality of paternal care, but few studies have addressed this subject. Taken together, our findings indicate that predictions on how reproductive site limitation affects several aspects of resource-based mating systems have weak empirical support. These predictions do not consider the plasticity in the mating tactics of males and females, which make them too simplistic. Moreover, since the original proposition of the mating system theory, our understanding of sperm competition increased a lot. We now know that accurate predictions on the intensity and direction of sexual selection should take into account both pre- and post-copulatory processes. Finally, the interplay between sexual selection and parental care is complex, and the original framework of mating system theory does not provide sufficient elements to derive clear and taxonomically broad predictions
A disponibilidade de sítios reprodutivos influencia tanto o comportamento de machos quanto de fêmeas em espécies cujo sistema de acasalamento depende da defesa de recursos. Usando uma abordagem meta-analítica, testamos cinco previsões direta ou indiretamente relacionadas à teoria de sistemas de acasalamento. Esperávamos que a limitação de sítios reprodutivos promoveria: (1) aumento na competição masculina pela posse de recursos; (2) aumento na variância do sucesso reprodutivo dos machos, gerando valores alto de oportunidade para a seleção sexual; (3) aumento da intensidade da seleção sobre características masculinas relacionadas à posse de recursos; (4) aumento no risco de competição espermática e (5) diminuição da qualidade do cuidado paternal. Compilamos informações de estudos observacionais e experimentais que compararam o comportamento reprodutivo de indivíduos da mesma espécie em situação de alta e baixa disponibilidade de sítios reprodutivos. Encontramos que, quando os sítios reprodutivos são escassos, há um ligeiro aumento na competição masculina, com maiores taxas de roubo de ninhos e interações agonísticas, e um ligeiro aumento no gradiente de seleção sobre características masculinas, com machos bem sucedidos tendendo a ser maiores do que machos mal sucedidos em monopolizar recursos. A disponibilidade de sítios reprodutivos não teve nenhum efeito consistente sobre a oportunidade para a seleção sexual e o risco de competição espermática. Entretanto, machos territoriais investiram mais em gônadas e perderam menos paternidade quando os sítios reprodutivos eram escassos. Não encontramos nenhum efeito da disponibilidade de sítios reprodutivos sobre a qualidade do cuidado paternal. Em conjunto, nossos resultados indicam que as previsões sobre como a disponibilidade de sítios reprodutivos influencia diversos aspectos de sistemas de acasalamento baseados na defesa de recursos têm fraco respaldo empírico. Tais previsões não consideram a plasticidade nas táticas de acasalamento de machos e fêmeas, tornando-as demasiadamente simplistas. Adicionalmente, desde a formulação original da teoria de sistemas de acasalamento, nossa compreensão sobre competição espermática aumentou. Sabemos atualmente que previsões acuradas sobre a intensidade e direção da seleção sexual devem levar em consideração processos pré- e pós-copulatórios. Finalmente, a interconexão entre seleção sexual e cuidado parental é complexa e a teoria original de sistemas de acasalamento não provê elementos suficientes para a construção de previsões claras e de amplo escopo taxonômico

AbstractThis chapter takes up the now infamous case of the so-called Macchariani Scandal in light of the Karolinska Institute’s tactics for maintaining and enhancing its position as a WCU. It pays special attention to research funding policies in general, and, in particular, the role of the chairman of the Institute’s Board of Trustees, the Liberal politician Lars Leijonborg, as an example of how the dream of becoming a world-class country in the increasingly fierce global competition can have far-reaching negative consequences for national higher education systems as well as for individuals.

The article discusses the importance of tactics in achieving superiority over the rivals in a sports competition. It is noted that tactical readiness is crucial in the confrontation of rivals, which have approximately equal indicators in other types of readiness. The interconnection of tactics and strategy of competition is shown. In this study, we used the method of theoretical analysis and generalization of data from special literature and the method of pedagogical observations of the sportsman-gamers’ competitive activity

This paper aims classify texts in humorous and non-humorous, while exploring the different parameters and tactics that can be used alongside the Support Vector Machine (SVM) classifier, to see and understand their impact on the classification and find the best combinations that have the best performances considering the accuracy and the F1 score. After observing the plots and analyzing the data we were able to come to a conclusion of which combination would be best to classify the texts in the testing data provided by the HaHackathon: Detecting and Rating Humor and Offense CodaLab Competition [cod 2021]. With those results we were able to give a wide view of this type of problem solutions, which can be used in further related work in this field of research.

The growing market demand for medical tourism has triggered intense competition among the medical tourism industry players. Word-of-mouth has been recognised as one of the key acquisition channels among the thoughtful marketing tactics to attract medical tourists. The purpose of this study is to gain insight on the relationship between medical service quality, perceived value, and satisfaction on word-ofmouth generation in a medical tourism setting. A quantitative survey was conducted to collect the data. The data collected was analysed using the Partial Least Squares Structural Equation Modelling (PLS-SEM). The results indicated that medical service quality is positively associated with perceived value, which in turn, affects satisfaction. However, perceived value and satisfaction are not positively related to wordof-mouth generation. The availability of resources, patient cooperation and collaboration among service providers do affect the outcomes of word-of- mouth generation. It is implied that effort must be directed by the healthcare institutions to enrich the value and satisfaction of medical services. Hospital management should emphasise the service quality and raise it to a high level in order to increase recommendation.

Increasing competition in the organizational environment and strengthening human capital can greatly contribute to the ability to close existing gaps in the development process and ensure a more competitive level, and the professional development process includes not only setting career goals and training agreements, but also evaluations and the feedback needed to assess progress. By optimizing nonverbal skills and forming impression management strategies promoted by psychological training in enhancing the knowledge and skills of police employees, they serve as a basis for organizational projects designed to facilitate self-realization of internal potential and stimulate their involvement in the organization. Organizational behavior is the study of the behaviors of individuals, which involves understanding, predicting and controlling human behavior, models and structures, in order to improve the environment, performance and efficiency of the organization. The original of this paper is that the research results led to the identification of components and mechanisms for producing change at the macro-, meso- and microsocial level, which uses a perpetual mobilization of social actors in organizations. Another novelty, for a wider geographical area of ​​scientific research, is the application of an intervention methodology in the training impression management strategies through nonverbal communication, with the purpose and purpose in developing relational skills and optimizing professional activity. The information obtained in research on nonverbal communication and impression management tactics on the organizational environment, can be applied for the development of programs for organizational counseling activities, business coaching and large-scale developmental training, promoted through managerial and corporate profile.
