Feature evolvable learning with image streams
Authors: Zheng Tianxiang , Wang Xianmin , Chen Yixiang , Yu Fujia , Li Jing
Published: June 2023

Feature Evolvable Stream Learning (FESL) has received extensive attentions during the past few years where old features could vanish and new features could appear when learning with streaming data. Existing FESL algorithms are mainly designed for simple datasets with low-dimension features, nevertheless they are ineffective to deal with complex streams such as image sequences. Such crux lies in two facts: (1) the shallow model, which is supported to be feasible for the low-dimension streams, fails to reveal the complex nonlinear patterns of images, and (2) the linear mapping used to recover the vanished features from the new ones is inadequate to reconstruct the old features of image streams. In response, this paper explores a new online learning paradigm: Feature Evolvable Learning with Image Streams (FELIS) which attempts to make the online learners less restrictive and more applicable. In particular, we present a novel ensemble residual network (ERN), in which the prediction is weighted combination of classifiers learnt by the feature representations from several residual blocks, such that the learning is able to start with a shallow network that enjoys fast convergence, and then gradually switch to a deeper model when more data has been received to learn more complex hypotheses. Moreover, we amend the first residual block of ERN as an autoencoder, and then proposed a latent representation mapping (LRM) approach to exploit the relationship between the previous and current feature space of the image streams via minimizing the discrepancy of the latent representations from the two different feature spaces. We carried out experiments on both virtual and real scenarios over large-scale images, and the experimental results demonstrate the effectiveness of the proposed method.
Pandemic techno-politics in the Global South
Authors: Firmino Rodrigo , Evangelista Rafael
Published: June 2023

Brazil has been standing out as one of the worst places on Earth to be during a global health crisis, especially for those whose struggle for basic humanitarian rights is already routine. How do the political environment and historical inequalities in countries like Brazil affect the ways in which public policy and technologies are framed as responses for the pandemic crisis? In this paper we aim to present the sequence of actions and omissions in the fight against sars-cov2 in Brazil, concentrating on measures based on the use of digital technologies and the sociotechnical arrangements unfolding in materialities that give shape to such measures. We will also discuss possible repercussions of the widespread adoption of surveillance technologies as a quick fix to the effects of the pandemic. Our focus is to explain how the materiality of the virus and its political as well as territorial effects are combined with digital technologies as responses (or lack of them) in the fields of healthcare, education, communication and labour in the context of the Global South.

Published: June 2023

Studying the grid integration of renewable energy power generation is crucial for achieving the goal of carbon neutrality since it may have a significant influence on the secure and reliable functioning of the power system. In order to solve the problem of deviation impact caused by renewable energy fluctuations and the optimal scheduling of VPP (Virtual Power Plant), the study divides the internal aggregation unit of the virtual power plant into two parts to model. One part is the source equipment, including wind power generation equipment, gas turbine, gas boiler and waste heat boiler. And the other part is the generalized Energy storage, including electric vehicles, air conditioners and alternative response loads. Ultimately, a generalized energy storage-based virtual power plant operation optimization model is developed under multi-market coordination of electricity-gas-heat-carbon. According to the study’s findings, adding more power-to-gas technology boosts revenue in the carbon trading market by 25.24 percent. The energy market’s revenue is equal to that in the absence of a carbon trading market, and the income of the natural gas market increases by $ 32.96. The income of the carbon trading market is $ 181.51, and the final operating cost is reduced by $ 180.80, a drop of 7.81%. To sum up, the suggested approach may more effectively achieve the best distribution of different energy sources, increase the dependability of VPP operation, and make it more low-carbon.

The optimization algorithms mimic the process of natural evolution. In watermarking, appropriate positions to insert the watermark is identified by the image that covers. These positions represent the populations of genetic algorithms. The major drawback in genetic algorithm are that it may get stuck-up at a local optimum while moving towards the best global solution and hence the result is poor when compared to other local optimization techniques. The proposed work based on Bandelet based biogeography firefly hybrid algorithms. The Number of pixels, Intensity of the pixel and contrast are considered for watermarking. The redundancy is reduced by Bandelet and used to determine the best location to embed the information into an image both locally and globally. Results of these techniques are compared based on coefficient correlation, index structural similarity, and noise ratio from peak signal.
ConSolid: A federated ecosystem for heterogeneous multi-stakeholder projects
Authors: Werbrouck Jeroen , Pauwels Pieter , Beetz Jakob , Verborgh Ruben , Mannens Erik
Published: June 2023

In many industries, multiple parties collaborate on a larger project. At the same time, each of those stakeholders participates in multiple independent projects simultaneously. A double patchwork can thus be identified, with a many-to-many relationship between actors and collaborative projects. One key example is the construction industry, where every project is unique, involving specialists for many subdomains, ranging from the architectural design over technical installations to geospatial information, governmental regulation and sometimes even historical research. A digital representation of this process and its outcomes requires semantic interoperability between these subdomains, which however often work with heterogeneous and unstructured data. In this paper we propose to address this double patchwork via a decentralized ecosystem for multi-stakeholder, multi-industry collaborations dealing with heterogeneous information snippets. At its core, this ecosystem, called ConSolid, builds upon the Solid specifications for Web decentralization, but extends these both on a (meta)data pattern level and on microservice level. To increase the robustness of data allocation and filtering, we identify the need to go beyond Solid’s current LDP-inspired interfaces to a Solid Pod and introduce the concept of metadata-generated ‘virtual views’, to be generated using an access-controlled SPARQL interface to a Pod. A recursive, scalable way to discover multi-vault aggregations is proposed, along with data patterns for connecting and aligning heterogeneous (RDF and non-RDF) resources across vaults in a mediatype-agnostic fashion. We demonstrate the use and benefits of the ecosystem using minimal running examples, concluding with the setup of an example use case from the Architecture, Engineering, Construction and Operations (AECO) industry.
Effect of short stem alignment on initial fixation, stress transfer, and failure risk

Published: June 2023

BACKGROUND: Short stems are advantageous for revision as they preserve autogenous bone. At present, the method of short-stem installation is determined based on the surgeon’s experience. OBJECTIVE: To provide the guideline for installing a short stem, we aimed to investigate the alignment effect on the initial fixation of the stem, stress transfer, and the risk of failure numerically. METHODS: Models in which the caput-collum-diaphyseal (CCD) angle and flexion angle were hypothetically changed based on the two clinical cases of hip osteoarthritis were analyzed using the non-linear finite element method. RESULTS: The medial settlement of the stem increased in the varus model and decreased in the valgus model. With varus alignment, the stresses acting on the femur were high in the distal to the femoral neck. In contrast, the stresses in the proximal to the femoral neck tend to be higher with valgus alignment, although the difference in the femur stress between varus and valgus alignment was slight. CONCLUSION: Both initial fixation and stress transmission are lower when the device was placed in the valgus model than in the actual surgical case. In order to obtain initial fixation and suppress stress shielding, it is essential to extend the contact area between the medial portion of the stem and the femur along the bone axis, and to ensure adequate contact between the lateral portion of the stem tip and the femur.

Published: June 2023

BACKGROUND: Patients’ self-efficacy levels are significantly associated with the process of recovery and creating social support in the inpatient recovery setting can help prevent post-stroke depression and anxiety. OBJECTIVE: To explore the current status of factors influencing chronic disease self-efficacy in patients with ischemic stroke, to provide theoretical basis and clinical data for implementing corresponding nursing interventions. METHODS: The study included 277 patients with ischemic stroke who were hospitalized in the neurology department of a tertiary hospital in Fuyang, Anhui Province, China from January to May 2021. Participants for the study were selected by convenience sampling method. A questionnaire for general information developed by the researcher and the Chronic Disease Self-Efficacy Scale were used for collecting data. RESULTS: The patients’ total self-efficacy score was (36.79 ± 10.89), which was in the middle to the upper level. Results of our multifactorial analysis showed that history of falls in the previous 12 months, presence of physical dysfunction, and cognitive impairment were all independent risk factors for chronic disease self-efficacy in patients with ischemic stroke (P< 0.05). CONCLUSION: Chronic disease self-efficacy in patients with ischemic stroke was at an intermediate to high level. History of falls in the previous year, physical dysfunction, and cognitive impairment were factors influencing patients’ chronic disease self-efficacy.

Behavioral optimization in Scientific Publishing
Authors: Watve Milind
Published: June 2023

Peer reviewed scientific publishing is critical for communicating important findings, interpretations and theories in any branch of science. While the value of peer review is rarely doubted, much concern is being raised about the possible biases in the process. I argue here that most of the biases originate in the evolved innate tendency of every player to optimize one’s own cost benefits. Different players in the scientific publishing game have different cost-benefit optima. There are multiple conflicts between individual optima and collective goals. An analysis of the cost-benefit optima of every player in the scientific publishing game shows how and why biases originate. By continuing with the current publishing trend, the global distribution of the scientific community would be increasingly clustered. Publication biases by gender, ethnicity, reputation, conformation and conformity will be increasingly common and revolutionary concepts increasingly difficult to publish. For a better future of science, it is necessary to design a publication system based on principles of human behaviour rather than on some ideological assumptions. If a system is designed in such a way that the conflicts between individual optima and collective goal are minimized, if everyone cares only for his/her personal benefits, biases would get minimized automatically and the progress towards the collective goal would be faster and smoother. Changing towards such a system might prove difficult unless a critical mass of authors take an active role to revolutionize scientific publishing.
Practical aspects of the application of cherenkov counting method with the correction of sample’s color quenching
Authors:   State Institution ", Buzynnyi M.G. ,   O.M. Marzіeiev Institute for Public Health of the NAMSU",   , Kyiv
Published: June 2023

Cerenkov counting is a convenient and effective method of counting high-energy beta radiation, which has long been used to measure a number of radionuclides, such as, in particular, 90Sr+90Y, in environmental objects. The traditional Cerenkov method requires the use of radiochemical sample preparation procedures, but these procedures may be simpler than those used, for example, for the liquid scintillation counting (LSC) method. We proposed the Cerencov method, which corrects color quench effect. The method is based on the correlation between the counting rates of the radiation of the sample and its external standard, which is observed for a wide range of color quenching of the samples. The use of such a Cerencov method allows measurement of high-energy -emitters, in particular, its use as an express method for the study of 90Sr+90Y in surface water. For a number of cases, the method makes it possible to avoid the use of long lasting and expensive sample preparation procedures. The results of the cross-testing of the samples obtained by the Cerencov method and direct measurement by the liquid scintillation counting method are in good agreement with each other.

The purpose of the work. Investigation of the physical characteristics of large geometric light video screens of dynamic advertising equipment as factors of possible adverse effects on visual analyzer of inhabitants of a surrounding housing. Results and discussion. Due to the development of outdoor advertising, the new generation of electronic panels can display video, multimedia, color, dynamic information, as well as quickly update advertising materials. This can cause an overload of the visual system and disrupt the normal functioning of brain, lead to visual fatigue. Studies of video screens on standardized parameters: lighting (lx), brightness (cd/m2) and non-standardized: lighting energy (mW/m2), color temperature (K), light pulsation (%) indicate their compliance with regulatory requirements of Ukraine and do not exceed levels regulated by other standards and recommended by the literature for sources of visible radiation. The exception is the angular size of the screen visible from the living room, which requires further studies. Conclusions. The use of geometrically large video screens of dynamic advertising equipment, especially in areas of dense housing and heavy traffic, requires improved methodological approaches to assessing the risks of visual discomfort and influence on public health.

Food Safety Attitudes in College Students
Authors:   ,   Andrews University, Booth Rachelle
Published: June 2023

College students are one of the most at-risk population groups for food poisoning, due to risky food safety behaviors. Using the Likert Scale, undergraduate students were asked to participate in a Food Safety Survey which was completed by 499 students ages 18-25. Data was analyzed using SPSS and AMOS statistical software. Four conceptual definitions regarding food safety were defined as: general food safety, bacterial food safety, produce food safety, and politics associated with food safety. Knowledge seems to be an important factor in shaing student's attitudes regarding general and bacterial activity. Ethnicity plays a role in how people view the politics of food safety, and perception of the safey of organic food.
Effect of Velvetleaf Root Exudates on Indole-3-acetic Acid Production by Rhizobium rubi AT3-4RS/6
Authors:   ,   Andrews University, Nadane Amy
Published: June 2023

Rhizobium rubi AT3-4RS/6 was isolated from the velvetleaf rhizosphere and is being tested as a potential biological control of velvetleaf. The purpose of this research is to test the levels of indole-3-acetic acid (IAA) produced by Rhizobium rubi AT3-4RS/6 after exposure to and incubation in velvetleaf root exudates. IAA production has been found in other rhizobacteria that are deleterious to weed growth. Velvetleaf seeds were sprouted and the roots suspended in a sterile mineral solution, which was then recovered and inoculated with R. rubi. Levels of IAA and numbers of viable bacterial colonies were then determined. The average level of IAA was .042 microgram/10(6) CFUs in the presence of root exudates and .1196 microgram/10(6)/ml, respectively. Results show that the presence of velvetleaf root exudates increased bacterial growth and reduced IAA production significantly (p<.05).

Every two years as part of the May Express program at Andrews University a small group of teachers and administrators take students to Tanzania, Africa on an educational tour. I attended this tour in both 2009 and 2011 and was able to use the knowledge provided by the course work as well as the personal experiences that I encountered in order to shape my own perceptions of Tanzania and its people, and the relationships that exist between their cultural practices and my own. To the Edge and Back Again: Tanzania as a People and a Place attempts to gather these newfound, and still developing, perceptions into a collection of creative non-fiction essays centered on Tanzania's fascination language, economy, wildlife, people, and cultural practices.
Mating Patterns and Breeding Success in the Larus Glaucescens-occidentalis Complex, Protection Island, Washington
Authors:   ,   Andrews University, Moncrieff Andre
Published: June 2023

Glaucous-winged gulls (Larus glaucescens) and Western gulls (Larus occidentalis) are found along the Pacific Coast. Where their breeding ranges overlap in Oregon and Washington they hybridize, producing a continuum of phenotypic variation. Whereas most colonies containing these hybrids are found on islands along the coast, several, including a large colony on Protection Island National Wildlife Refuge, WA, are located in the Salish Sea. In 2010 I scored the henotypes of 81 gull pairs at the Protection Island cology using an index based on plumage melanism and bare-part coloration. Gulls from the entire range of phenotypes in the L. glaucescens-occidentalis complex, from putatively pure L. glaucescens to putatively pure L. occidentalis, bred on the colony, although most gulls appeared more like L. glaucescens. Significant assortative mating based on phenotype occured on the colony, but a small number of L. occidentalis-type pairs appeared primarily responsible for this trend. Although the mass of the third egg in the clutch was significantly less for pairs with increasingly L. occidentalis-like males, I observed no significant difference in hatching success or clutch size across the range of phenotypes.

Published: June 2023

The goal of my research was to evaluate procedures currently used in the Intracellular Leech Lab in order to modify the Neurobiology ZOOL475 Lab to increase the rate of successful intracellular recordings for future Neurobiology students. Two approaches were used: the first was to evaluate the possibility of using a less expensive leech species in order to allow students unlimited attempts at recording from ganglia without budget constraints. The second was to evaluate various raising conditions (water, temperature, and age) to optimize the quality of the leech ganglia. Both approaches provided useful information to improve lab success.
No. 334: A Visual Exploration of Race and Identity
Authors:   ,   Andrews University, Pierre Naudline
Published: June 2023

Throughout history, humans have invented several methods of classification - most of which are unsettling. The human need to classify is one that is deeply rooted in the search for identity. The need to fit, the need to explain, and the need to rationalize the world around us is a powerful incubator in which the process of human classification takes place. Although this thesis project involves a substantial amount of research, it is essentially a documentation of my journey to finding my identity through the lens of human classification based on physical attributes. Through the research of various human classification system such as scientific racism and somatotyping, and through the creation of a compelling body of work, I want to both inform and disturb the viewer while raising questions about classification, race, and identity.
The Effects of a Valproate Fatty Acid Prodrug on the Inositol Biosynthetic Pathway
Authors:   ,   Andrews University, Kang Gina
Published: June 2023

Bipolar disorder is characterized by alternating episodes of mania and extreme depression. Compounds such as omega-3 fatty acids and valproate individually treat symptons of bipolar disorder, one of which is elevated inositol levels. Lithium and valproate are known to reduce iniositol levels. The goal of this project is to combine linoleic acid (an omega-3 fatty acid substitute) with valproate and observe the prodrug's effects on the inositol biosynthetic pathway using Saccharomyces cervisiae yeast as the model system. Since inositol is required for growth, the effects of the prodrug on the inositol biosynthetic pathway was determined by comparing its impact on the growth of wild type yeast cells that overproduce or lack the production of inositol.
A Search for Clarification: Contemporary Views of the Inspiration and Authority of the Bible in Seventh-day Adventism
Authors:   ,   Andrews University, Swenson Michael
Published: June 2023

Within Seventh-day Adventism there is recognizable theological diversity on a wide variety of issues. One major reason for that has to do with the different ways Adventists view the inspiration and authority of the Bible with particular suppositions. In order to elucidate the given problematic, I will present a comparative analysis of four thinkers and outline their respective perspectives: Fritz Guy, Alden Thompson, Fernando Canale, and Samuel Koranteng-Pipim. As I will suggest, each thinker represents either a progressive, moderate, traditional or literatistic approach to interpreting the Bible. By clarifying their positions I will investigate their views of inerrancy, their perception of the influence of cultural determinism and historicism in Scripture and contemporary interpretations, and their willingness to consult sources besides the Bible for their theological thinking. I will demonstrate that their hermeneutical methodology shapes how they think about and develop doctrines, beliefs, and practices.
A Language Without Words: Music as an Agent of Identity in Brian Friel's Dancing at Lughnasa
Authors:   ,   Andrews University, Tetz Catherine
Published: June 2023

Music has consistently played a major role in the work of Irish playwright Brian Friel and provides a steady backdrop for Dancing at Lughnasa (1990), a memory play about a family in Northern Ireland struggling to stay together in the August of 1936. This paper examines the function of music within the context of the play to see how it heightens the themes of identity, otherness, and memory.

Authors:   ,   Andrews University, Payne Brianna
Published: June 2023

Galápagos marine iguanas (Amblyrhynchus cristatus) briefly forage in marine habitats but spend their remaining time hauled out on land. A wide range of diurnal activities, from social and thermoregulatory behaviors to sleep and food processing, occurs during haulout. To understand the dynamics of haulout and foraging in relation to environmental factors, I fit compartmental models derived from ordinary differential equations to field data collected daily from 30 April to 16 May 2011 at two sites—one Sandy and one Rocky—at Cabo Douglas, Isla Fernandina. The best model for haulout at the Sandy site accounts for 77–80% of observed variability and includes the environmental variables solar elevation, heat index, tide height, and relative humidity. Using only the predictable variables of solar elevation and tide height, the model still accounts for 72% of system variability. The best model for haulout at the Rocky site includes solar elevation, THW index, tide height, and hour of day, and accounts for 57% of observed variability. Using only solar elevation, tide height, and hour of day, the model still accounts for 51% of the variability. Poisson regression supports these results with few inconsistencies and provides further insight into system dynamics. Although the environmental variables that predict haulout are different across sites, the methodology is powerful and could benefit conservation measures developed for this endemic species.

Vector Marketing Corporation, an established direct sales company, has strong sales and recruiting programs. The goal of this research is first, to analyze the effectiveness of Vector's sales and recruiting programs and second, to assess variations of the application of the Vector business model to other businesses. For easier comparison and analysis, Vector's business model was divided into nine segments. This business model was then applied to the operations processes of Goodwill, Amway Global, and Andrews University School of Business Administration (SBA). While findings indicate useful applications for all three businesses, the strongest results pointed to Amway Global and Andrews University SDA using Vector programs to increase their recruiting and operational efficiency.
Addressing Socio-Economic Challenges to Curb Youth Participation in Terrorism in Africa
Authors: Tlou Tendaishe
Published: June 2023

The scourge of terrorism has become an international crisis after the 9/11 attacks in America. Terrorism has deeply encroached its claws in Africa on the premise of socio-economic challenges along the clash of civilizations. In countries such as Nigeria, Somalia, Central African Republic, Kenya and the Maghreb region, terrorism is a threat to peace and security, compounded by spiraling youth unemployment rates, the youth bulge, porous borders, poverty, arms proliferation, weak governments, economic problems among other challenges. It is yet to be seen how Africans will unite to deal with this threat to security on the continent given the above mentioned problems. At the same time, one will assess the ramifications, advantages, and pitfalls of the youth bulge and foreign intervention to curb the spread of terrorism towards obtaining sustainable peace and security on the continent.

Young African Leaders Forum (YALF) Developmental Projects
Authors: Abila Tera
Published: June 2023

The Young African Leaders Forum is actively engaged in developmental projects that would see a sustainable Africa in the near future. The young leaders have committed themselves to undertaking specific projects in their countries. These projects keenly focus on playing a major role in the achievement of Sustainable Development Goals and the African Union’s Agenda 2063. YALF passionately undertakes these developmental projects because we believe that Africa has the enormous potential to empower her people and ensure her challenges are solved in an amicable manner. The youth leaders have dedicated themselves to serving voluntarily in their communities and this has invoked a sense of patriotism in the leaders. This is because YALF believes that it is only through volunteerism that persisting problems can be fully tackled.
Pan-Africanism, Leadership Prospect and the Agenda 2063
Authors: Ifoh Prince
Published: June 2023

The idea of development has always been nurtured. It is as old as the history of Africa itself. Even though the continent is believed to host the starting point of development, man has struggled to continue doing so there. Shying away from reality will not be the solution, but facing reality with all its encumbrances. Perhaps, many people are ignorant of what pan-Africanism can offer; hence, they relegate pan-Africanism and the African development prospect to mere academic studies. Against this backdrop, the paper seeks to substantiate the significance and role of pan-Africanism in the development of Africa.
Education: A Pathway to Africa's Development (The Scrutiny)
Authors: Lululukile Ngulube Walusungu
Published: June 2023

There have been many theories given on how Africa should develop, regardless, this paper argues on why it is important to focus on education as one of the major tools to move Africa forward. It scrutinizes the current education systems in African countries and how they are not tailored to equip the African child with the mindset and skills required for leadership. Instead of waiting for aid and relief, this paper champions the need for Africans to arise and offer solutions to Africa's problems. The challenge calls for stock-taking of the “state” of the different African countries so that the proper education system can be targeted to them. For Africa's education system to respond to the needs of poor children and to contribute to wealth creation in communities and society at large, it needs to take poverty into special consideration when planning education services.
СХІДНА ГАЛИЧИНА І ЗАХІДНА ВОЛИНЬ: ОСОБЛИВОСТІ КУЛЬТУРНО-ОСВІТНЬОГО І СОЦІАЛЬНО-ЕКОНОМІЧНОГО СТАНОВИЩА У МІЖВОЄННІЙ ПОЛЬЩІ
Authors: Зуляк Іван , Макар Юрій
Published: June 2023

Після Першої світової війни, з розпадом імперій, західноукраїнські землі відійшли до Польщі, Румунії та Чехо-Словаччини. У складі міжвоєнної Польщі вони становили третину всієї території. З одного боку, вони стали джерелами сировини, дешевої робочої сили та ринками збуту товарів, з іншого – спричинили появу і загострення зовнішніх та внутрішніх проблем, що суттєво дестабілізували ситуацію. Між українцями, які проживали в різних регіонах, існували відмінності у рівні національної свідомості, політичної й культурної активності, що власне використовувала влада, відмежовуючи так званим «сокальським кордоном» Східну Галичину від Західної Волині, існування якого було результатом релігійних, культурних, економічних й особливо політичних причин. Ревіндикаційна реформа була однією з форм асиміляції українців, що використовувала їх етнічну строкатість, передбачала «штучне» прилучення лемків, гуцулів, поліщуків, які не мали чіткої національної приналежності, до польської релігійної і культурної системи. Власне з цим пов’язується акція організації так званої «заґродової шляхти» під гаслом «навернення» до польської нації українців, передусім селян, які нібито відійшли від свого народу в результаті наступу Греко-Католицької Церкви, недостачі костелів тощо. Відзначалося активністю «Сторонніцтво людове», зважаючи на аполітичність місцевого селянства, висуваючи фальшиві гасла «за вашу й нашу хлопську вольність». Однак найбільш послідовними були польські державні інституції в ліквідації української мови, культури й шкільництва, запроваджуючи утраквістичні навчальні заклади. Соціально-економічна політика міжвоєнної Польщі гальмувала розвиток Східної Галичини і Західної Волині, перетворивши їх на аграрно-сировинний придаток до корінних польських земель. Основою промислового виробництва були сировинні галузі – нафтоозокеритна і лісова. Певне значення мала переробка сільськогосподарської та мінеральної сировини. Положення урядової земельної реформи вимагали щорічного розпарцелювання значних обсягів землі, натомість влада проводила незначну парцеляцію на корінних польських землях, на «кресах» запроваджувала цивільну колонізацію та військове осадництво, коли кращі землі, передавалися полякам, переважно відставним військовим. Осадники мали сприяти полонізації українців і в разі потреби виконувати каральні функції. Жорстка соціально-економічна політика, що її проводила влада, призвела до страйків і навіть збройних заворушень. Відповіддю уряду була кампанія пацифікації, так зване «умиротворення», за допомогою поліції та війська, що стало причиною використання українцями більш радикальних засобів протистояння владі.
