“I Would Prefer Not To”: Establishing the Missing Link between Invalid Voting and Public Protest in Latin America

ABSTRACTWhile invalid voting is often treated as protest behavior in an electoral context, its association with actual political protests has not yet been empirically demonstrated. The relative scarcity of research on the topic is likely due to the hybrid nature of invalid voting as a both formal and informal political gesture. The novel availability of event-based data for public protests in Latin America allows for testing whether their occurrence is connected with changes in spoiled and blank ballots. Using an appropriate dynamic regression model covering variations in the 148 intervals between Latin American legislative elections in the 1979–2021 period, this study finds a strong connection between the emergence of antigovernment protests and surges in invalid voting (and vice versa). This relationship still holds at parity of economic conditions and it is reinforced by a lack of alternation in the party of power. Conversely, the appearance of workers’ strikes appears to work as a substitute for this behavior, which is also chosen by voters when democracy deteriorates, while corruption has no independent impact on invalid voting. Overall this work’s findings promise to send the research agenda on invalid voting in a new direction, previously unexplored because of an absence of fitting data.

A Convolutional Neural Network Based Robust Automated Real-Time Image Detection System for Personal Protective Equipment

Statistically, casualties in engineering workplaces often result from one of the following accidents: when people get stuck in the rotating machines, electric shocks or collision with heavy equipment. Most of these accidents can be prevented if the workers make proper use of personal protection equipment (PPE). This paper presents the design and implementation of a functional image detection system that takes a picture of an employee, analyses it, and determines the employee he is appropriately attired to enter a potentially hazardous workplace. This system can help to reduce the liability of company owners, by extension their costs, and can provide level of accident prevention. In this study, a convolutional neural network (CNN) was used to develop three sets of models, namely hard hat model, boot model, and vest model. These were used to detect the appearance of workers and determine if the PPE being worn was in compliance with the stipulated requirements for entry to a particularly hazardous workplace. To determine the performance of the system, each model was validated with two classes of image datasets: normal colour RGB (Red, Green and Blue) and grayscale image. The overall average accuracy of the system, in real-time implementation, then was calculated and determined to be 83.33%.

프랜차이즈 미용업의 경영성과 결정요인에 관한 연구

뷰티산업의 발전으로 인해 미용업계도 대형화, 전문화, 프랜차이즈화 되고 있는 시점에서 미용업에 대해서 매출액을 결정짓는 요인들을 AHP를 통해 분석하였고 분석한 결과 프랜차이즈 미용업의 경영성과 결정요인인(입지조건,매장시설,프랜차이즈브랜드,인적구성,가격수준)에서 상위계층에서 인적구성(0.313)과 하위계층에서 연계시설(0.326)을 실증분석을 통해 확인할 수 있었으며 종합적으로 입지조건, 인적구성, 프랜차이즈브랜드 순으로 나타났다. 이러한 연구결과는 향후 프랜차이즈 본사에서 점포개발을 함에 있어서 실무적으로 도움이 될 것으로 판단이 되며 다른 업종에서도 동일한 연구방법으로 실증연구가 가능하다고 판단된다. The importance of the factors that influence on the sales from the owners of franchise beauty salons has been analized through AHP method. The result shows that the critical factors are workers, location, franchise brand power, facilities and price in turn. The importance of the low level shows that facilities, famous staffs, the appearance of workers, franchise brand's populality in turn.

Caste Differentiation Pathways in the Neotropical TermiteArmitermes holmgreni(Isoptera: Termitidae)

The present study investigated the caste differentiation system of Armitermes holmgreni in natural colonies from the Atlantic Forest in northeastern Brazil. Thirteen measurements were made of the termites encountered in three colonies. The morphometric differences among the instars were analyzed using principal component analysis (PCA). The differentiation patterns of the nymphal lineages of A. holmgreni agreed with earlier descriptions of species of the Termitidae family, with one larval instar followed by five nymphal instars and alates. Nymphoid neotenics became differentiated starting at the fourth or fifth nymphal instar. Two larval instars were observed in the apterous lineage before the appearance of workers, presoldiers, and soldiers. Both workers and soldiers had only one instar each. The A. holmgreni workers consisted of male and female individuals, without sexual dimorphism, a situation that had not been previously recognized among the Syntermitinae. The A. holmgreni soldiers consisted only of female individuals, a pattern observed in most species of Termitinae and Macrotermitinae. The differentiation of nymphoid neotenics starting at the fourth or fifth nymphal instar has also been reported for Armitermes euamignathus. The general patterns of differentiation of A. holmgreni were similar to those previously observed in other species of Syntermitinae.

Influences on the density and dispersion of bumble bee nests (Hymenoptera: Apidae)

To determine some of the influences on nesting densities of bumble bees I examined the dispersion and occupancy of 35 nests in an old field on Amherst Island, Ontario, Canada and 39 nests found by Cumber (1953) in England. Densities up to 1 nest per 200 m2 were observed. Overall, Cumber's nests were randomly dispersed, but nests on the ground surface were aggregated. Nests of surface‐nesting species were consequently more aggregated than expected at random, whereas surface‐nesting and underground‐nesting species seldom nested near one another. This distribution of nests probably reflects the nesting habits of the rodents that originally constructed the nests, rather than interactions between bees. On Amherst Island, abnormally wet spring weather apparently hampered normal colony development, particularly of underground‐nesting bees based on a low frequency of underground nests, scarcity of workers of two underground‐nesting species compared with the relative abundance of spring queens, and delayed appearance of workers of all species relative to the previous year. The nests of two common species were randomly dispersed, but those of a third species were regularly distributed, suggesting that intraspecific interactions may limit nesting density for this species.

Conflict of Revolutionary Authority: Provisional Government vs. Berlin Soviet, November-December 1918

The Russian revolutions of 1905 and 1917 saw the first appearance of workers' and soldiers' councils, called Soviets. In 1917 the Executive Committee of the Petrograd Soviet, acting for all the Russian Soviets, became the chief competitor of Kerensky's Provisional Government. The Bolsheviks, employing the slogan “All Powers to the Soviets”, used the Petrograd Soviet in their drive for power. In the October Revolution the Soviets, dominated by the Bolsheviks, replaced the Provisional Government as the government of Russia.
