The article discusses methods of increasing the efficiency of information communication radio systems of mobile communication, which includes increasing spectral efficiency and energy efficiency when used for telecommunication radio equipment. A comparison of block error coefficient values for f-OFDM, W-OFDM and OFDM methods with mixed numerology of uplink and downlink subscriber channels of access to information resources of the telecommunications network was made. As a result of the study of compression methods using several carriers, the dominant compression method for mobile communication systems, in particular, the CP-OFDM method due to its high efficiency of spectrum use, scalability and flexibility due to the introduction of a cyclic prefix, has been determined. It is proved that the CP-OFDM compression method is free from the Doppler range shift problem, thus the range and Doppler shift estimations can be considered as independent tasks in CP-OFDM. In addition, CP-OFDM parameters such as carrier distance, guard interval size, frame length, and pilot shape can be tailored to optimize the performance and robustness of detection and data transmission. However, such advantages are based on perfect synchronization (time and frequency) between the transmitter and receiver – although perfect synchronization may not be possible, especially for bistatic scanning, where the transmitter and receiver of the scan signal are not adjacent. In this case, the cyclic prefix may not provide any advantage for quality scanning, and multiple unprefixed waveforms may be considered. The main disadvantage of rejecting the prefix is the difficulty of data detection (due to intersymbol interference), which must be eliminated. Another important challenge for scanning, where energy efficiency is extremely important, is the large PAPR of multi-carrier (prefixed or unprefixed) signals. Single-carrier compression methods, which are based on the expansion of the code area of common radar signals and communication, in which the radar characteristics are affected by sequence autocorrelation, have been studied. However, the long spreading code, which leads to good autocorrelation, reduces the spectrum utilization efficiency for communication systems. In this case, the estimation of the Doppler effect is not trivial and requires more complex algorithms. The justification of the choice of the signal modulation scheme in 5/6G radio systems has been made.

The use of natural clays in production and environmental protecting measures is provided by their mineral compounds, physical and chemical properties which are defined by the composition and size of clay part. In terms of ecology that is expedient, as the clay minerals almost don’t have compounds that pollute waters and they are natural for such areas. It has been investigated the problems of the Ukrainian market of petroleum products and suggested the ways to solve them by developing of a program for the transition to Euro environmental standards and alignment of Ukrainian standards with the European ones. The influence of the granulation process on the sorption properties of the obtained granulated aluminosilicates has been investigated. The main operational characteristics of the received saponite granulate namely: the stability and strength of the granules in gasoline over a given period of time; it has been evaluated the water resistance and oil capacity of sorption materials based on layered aluminosilicates. It has been shown that the activation of natural sorption materials with acids does not significantly affect the indicators of heat resistance and destruction processes in the saponite-activator system. Moreover, granulation improves the strength and filtration characteristics of natural sorbents by increasing the filtration rate. The results of the research allow us to recommend the obtained sorbent materials as an efficient filtering charge for cleaning and controlling specific properties as a filter load for cleaning hydrocarbon mixtures and for obtaining high-quality, high-octane and low-toxic fuels. It was established that the obtained sorption material based on saponite clay improves the basic exploitative characteristics of the fuel. Its application allow to solve the problem of reducing toxic emissions of e.g. motor vehicles in atmosphere.

Published: May 2023

The paper examines the process of building and functioning of the system for identifying terms and abbreviations in text documents. The task of developing such a system is urgent, since such an identification problem often arises in the military sphere. During the implementation of the system, it was taken into account that a single term or abbreviation may have several explanations in different regulatory documents. All available explanations are added to the term or abbreviation, which is taken into account during the operation of the system. A feature of the system is the use of natural language processing methods, since terms can be found in different cases. To implement the system, ready-made Python packages were used to cover similar tasks: Tkinter, PyMuPDF Examples of the system’s functioning are given. The developed system is used in practice. In the process of completing the work, the research of problems and the search for solutions for the tasks is carried out, an information system is developed for the processing of documents with the aim of integrating definitions of potentially unknown terms and abbreviations into them, in order to enable officers to use any literature without problems, because all terms and abbreviations will be known. To generalize the documentation, all the necessary requirements for the system are defined, and in order to correctly create the architecture and allocate the functional tasks of the system under development, a system analysis is performed and a conceptual model is built. Using all the specified information, all the necessary diagrams are built using the UML notation. Diagrams depict the relationships between objects and the overall architecture of the system. The architecture of the system is built in such a way that the component systems and the system as a whole can be easily expanded. At the end of the development, testing and implementation of the project is carried out. The process of operation of the components of the system on the part of the end user and the process of deployment by the end user of the information system are described. The object of the study is the presence of slowing factors in the process of command and control carried out by commanders of tactical units, which can slow down decision-making and also affect their correctness. The subject of the study is to solve the problems of the appearance of slowing factors in the process of command and control carried out by commanders of tactical units, by means of work with military data.

The technology of manufacturing leather material for the upper of shoes from semi-finished chrome tanning obtained from raw cow hides been has been developed. The technology at the filling-plasticization stage involves the use of a syntane-tanide composition modified with alkylcarboxyethanolamine of aliphatic acids of fraction C7–9. The filling and plasticizing composition includes syntanе BNS TU 17-06-165-89 and mimosa extract tanids with a content of the main substance of 81.7%. The semi-finished product is plasticized with Fosfol L-1301 emulsion of Cromogenia Units, S.A., Spain. Chemical reagents in the structure of the material are fixed by potassium alum modified with sodium formate. All previous and subsequent processes and operations are performed according to the industrial technology of the enterprise “Chinbar”. The resulting semi-finished product is characterized by a volumetric yield of 256 cm3/100 g of protein, a specific surface area of 71 m2/g, which are 8.0 and 11.0% higher than the industrial sample. Deformation properties of topographic areas and coefficients of uniformity of topographic areas of leather materials at loads of 10.0 MPa and rupture were calculated. At the same time, a more effective characteristic of the homogeneity of the material structure is the uniformity factor at a load of 10.0 MPa. The leather material obtained by the experimental technology has a uniformly oriented structure with an arithmetic average coefficient of uniformity of 1.0, and the industrial material has a transversely oriented structure with an arithmetic average coefficient of uniformity of 0.83. The advantage of the experimental material over the industrial one in terms of the complex of physico-chemical and technological properties and the coefficient of uniformity increases the efficiency of its use for the manufacture of leather products. The obtained leather material meets the requirements of DSTU 2726-94 “Leathers for shoe uppers. Specifications”.

High productivity when performing finishing technological operations, as well as technological processes of mixing loose fine-dispersed substances, can be achieved with the use of equipment in which working containers perform complex spatial movement. To date, various types of developed felting machines with complex spatial movement of working containers are known. Each type of such equipment corresponds to the implementation of various felting technological operations – separation of parts from sprues, grinding or polishing of products, cleaning of metal parts from corrosion or mixing of loose fine-dispersed substances. During the operation of the rolling equipment, various reactive loads arise in the kinematic pairs, which depend on the design features of the machines. With the use of the automated design system “SolidWorks”, 3D modeling and further strength research of a model of a rolling machine with a working capacity with complex spatial movement and variable volume was performed. In the kinematic chain of the machine under study, an additional moving connecting rod link with rotational and translational kinematic pairs is used. During the performance of the force study, the reactions in all rotational and translational kinematic pairs were determined, the influence of the change in the interaxial distance of the working capacity and the additional moving link of the connecting rod on the maximum values of the reactions in the kinematic pairs of the machine was investigated. The presented results of analytical studies can be applied in the relevant design bureaus of machine-building enterprises at the stage of designing equipment with complex spatial movement of working capacities and felting technological processes.

Fixed assets are tangible assets that have a useful life of more than 12 (twelve) months to be used in government activities or utilized by the general public. Regional asset management is part of regional financial management covering all activities covering needs planning and budgeting, procurement, use, utilization, security and maintenance, appraisal, transfer, destruction, write-off, administration, and development, supervision and control. The management of fixed assets at the Regional Financial Board (BKD) of Tanah Datar Regency needs to be carried out properly and optimally in order to achieve good fixed asset management. The Tanah Datar Regency Regional Financial Board has several obstacles in carrying out administration, namely in carrying out capital expenditures related to fixed assets because in that year the Tanah Datar Regency Regional Financial Board did not record the time the capital expenditure process occurred. The purpose of this study was to find out whether the management of fixed assets is in accordance with Permendagri No.19 of 2016 at the Regional Financial Board (BKD) of Tanah Datar Regency. The type of research that the researchers did was field research with a qualitative approach. The data sources that researchers use are primary data sources and secondary data sources.

Background: The current lack of effective drug therapies for Alzheimer’s disease (AD) has prompted researchers to seek alternative nutritional therapies, such as medium chain triglycerides (MCTs). However, results are inconclusive. Objective: This systematic review and meta-analysis aims to summarize current evidence on the effect of MCT on cognitive function in patients with mild cognitive impairment (MCI) or AD. Methods: A systematic search was conducted up until December 16, 2022, to identify human interventions reporting the effects of MCT on cognitive functioning of MCI or AD patients. 995 non-duplicated publications were identified, of which nine (n = 10 studies) met the inclusion criteria. Results: Meta-analysis showed cognitive improvements in general (SMD = 0.64; 95% CI [0.05, 1.24]), but not in memory, language, and attention domains after oral MCT administration, compared to placebo. The effect of MCT was greater among APOE ɛ4 (−) subjects than APOE ɛ4 (+) subjects (SMD = 1.87; 95% CI [0.35, 3.40]). Conclusion: This review provides some evidence that treatment with MCT could improve general cognitive function in APOE ɛ4 (−) cognitive impaired patients. Better characterized clinical studies are warranted before making a definitive conclusion on the use of MCT for MCI and AD management.

Low birth weight (LBW) is an important indicator of maternal health and poverty. This study explored the socioeconomic factors associated with LBW. METHODS: Data was collected from a 4-year maternal-newborn registry. RESULTS: There were 5,316 LBW and 54,029 normal birth weight (NBW). The prevalence of LBW was 9%. The Native women in the LBW group compared to non-native women were 10.4% (1784/5316) vs. 8.4% (3532/5316) with a P-value of 0.001. There were more illiterate mothers in the LBW compared to the NBW, respectively: 8.1% (1597/19497) vs. 7.5% (1763/23230) with a P-value of 0.001. Working mothers tend to have more LBW infants compared to mothers with NBW, 8.4% (1588/17217) vs. 7.9% (2532/31891) and P-value 0.001. Young mothers (<20 years old) with early childbearing had more LBW compared to older mothers, respectively 12.7% (180/1414) vs. 8.9% (5149/52919) P-value <0.001. Women with no antenatal care reported a high rate of LBW compared to women with regular antenatal care: 14.2% (516/3696) vs. 8.6% (4741/55691) P-value <0.001. LBW babies were born more from assisted conception pregnancies (38% compared to 8.4% of normal pregnancies) P-value <0.001. Smoking mothers scored higher with LBW at 13.6% vs. 8.3% and a P-value of 0.001. There were no differences between the two groups regarding religion, consanguinity, marital status, or family income. CONCLUSION: Risk factors for low birth weight can be improved by providing antenatal care, smoking cessation, optimizing high-risk pregnancy care, and governing assisted reproduction regulations.
Motorist disorientation syndrome; clinical features and vestibular findings
Authors: Ainsworth Carolyn , Davies Rosalyn , Colvin Ian , Murdin Louisa
Published: May 2023

BACKGROUND: Motorist Disorientation Syndrome (MDS) is a term used to describe patients who primarily experience symptoms of dizziness/disorientation whilst in a motor car [21]. There is uncertainty about the relevance of vestibular dysfunction and whether this disorder could instead be a visually induced dizziness (VV) or part of a functional disorder similar to Persistent postural perceptual dizziness (PPPD). OBJECTIVE: We present the largest case-series to date of patients whose main complaint is of illusions of movement of self/vehicle when driving, characterising features of this group. METHODS: 18 subjects underwent detailed clinical assessment including validated questionnaires. A subset of patients underwent vestibular function testing. RESULTS: Mean onset age was 42 years, with no gender preponderance. Mean symptom duration was 6.39 years and was significantly longer in women. 50% reported moderate or severe handicap. Vestibular abnormalities were found in 60% of subjects tested. There was no significant difference in VSS total score between those with MDS and vestibular migraine (p = 0.154) with both having higher scores than healthy controls (p = 0.002, 0.000 respectively). CONCLUSIONS: MDS represents consistent symptoms, with high symptom burden, comparable to vestibular migraine. Vestibular deficits were not a consistent feature and similarities to VV and PPPD exist.

Sorghum bicolor is an important grain species used for food and feed production, where P is a key element/nutrient in grain production. The effect of increasing phosphorus doses to grain sorghum in Cerrado soil with sandy texture and low fertility in Cerrado conditions was evaluated. The study was conducted at the Pântano Farm, Jataí, Goiás, Brazil. The sorghum cultivar used was AG 1085. The doses of 0 (control), 40, 80, 120, and 160 kg ha-1 of P2O5 were used, whose source was triple superphosphate 46% of P2O5, with five replications each, designed in random blocks. The evaluated variables were stem length, stem diameter, leaf area, shoot dry mass, leaf phosphorus content, nutrient accumulation, fertilization efficiency, chlorophyll a, and chlorophyll b. For the variables shoot dry mass in (g plant-1), leaf phosphorus content, dry mass expressed in (kg ha-1), and chlorophyll b (CFI), the effect for the application of P doses in cultivar had a linear effect. The analysis of variance of the regression showed a quadratic effect for the variables stem length, stem diameter, leaf area, and phosphorus use efficiency, and for chlorophyll a (CFI), showing a maximum point at the best dose and best values ​​of the variables. The application of Phosphorus influenced the development of the grain sorghum cultivar. The 129 kg ha-1 of P2O5 had the highest efficiency of phosphorus fertilization corresponding to 82.02%.

Подано результати досліджень стосовно забезпечення військ (сил) логістики, транспортної логістики та побудови автоматизованих інформаційних систем. Успішне планування, проведення та підтримка військових операцій вимагає відповідних підходів. Аналіз стану транспортної логістики Збройних Сил України дозволив виявити основні її проблеми: неефективне використання маршрутів доставлення озброєння, техніки, особового складу від баз зберігання (місць дислокації) до місць виконання бойових завдань; незадовільний стан автомобільних доріг (шляхів підвезення), особливо у зонах бойових дій; слабка транспортна інфраструктура; недостатня кількість уніфікованих місць розвантаження/завантаження, а також їх низький техніко-технологічний рівень; відсутність практично на всіх видах транспорту сучасних інформаційно-телекомунікаційних засобів, що відповідають світовим стандартам (gps-навігатори, бортові комп’ютери тощо); відсутність сучасного вітчизняного програмного забезпечення, яке застосовується у транспортній логістиці військового призначення; високий рівень фізичного і морального зношення рухомого складу транспорту військових частин та підрозділів; неефективне використання рухомого складу організацій (фірм) перевізників, сил логістики та безпосередньо бойових підрозділів (необхідність подальшого впровадження аутсорсингу); втрати від простою в очікуванні завантаження/розвантаження транспортного засобу; недовантаження рухомого складу; складності організації взаємодії декількох видів транспорту; втрати від незаконних дій особового складу; низька продуктивність транспортної сфери через слабку систему мотивації та/або низьку кваліфікацію особового складу; відсутність необхідної кількості фахівців з транспортної логістики військового призначення. Одним з основних висновків дослідження є те, що велике значення для ефективного впровадження логістичного підходу на транспорті, особливо у військовій сфері, має наявність і модернізація спеціалізованих автоматизованих інформаційних систем та відповідного програмного забезпечення, що можливе за умов розробки науково-методичного апарату.

The reutilization of waste plastic in asphalt binders and mixtures has become a popular field of research as the global scientific community looks to find avenues for the effective and efficient recycling of waste plastic. The motivating factors behind reutilizing waste plastic in asphalt include reducing the environmental impact of waste plastic and realizing potential economic savings due to performance enhancement, as shown in the early research studies. There are currently several key remaining challenges to overcome before the widespread deployment of waste plastic in asphalt pavements can occur. For instance, the addition of widely available Polyethylene (PE) to the asphalt binder often results in issues with binder storage stability due to its differing density compared to the asphalt binder, its non-polarity, and inert nature. A common solution to prevent separation is the addition of a reactant that would interact with the modifier (waste plastic) to prevent any phase separation. This study examines the effects of Reactive Ethylene Terpolymer (RET) and Ground Tire Rubber (GTR) on the storage stability of the PE-modified binder. Binder test results showed RET significantly improved PE-rich modified binder storage stability, while GTR did not. The effect of phase separation was tested in asphalt mixtures to observe any correlations between storage stability and asphalt mixture performance. A scaled-up version of a separation tube was utilized with dimensions 170 mm length, 90 mm diameter, and PE19 modified binder was stored in the tube for 48 hours at 1630C, akin to standard D7173 (storage stability standard). Upon completion of 24 hours of freezing, the binder was sampled from the top and bottom of the scaled-up separation tube, discarding the middle part. Asphalt mixtures were produced using the modified binder sampled at different heights of the separation tube and tested for rutting and cracking potential with the Hamburg Wheel Tracking Test (HWTT) and Disk-shaped Compact Tension Test (DCT), respectively. At the same time, improvements to both high and low-temperature mixture performance were observed in most formulations considered compared to the control 1 mixture; the test repeatability varied as a function of the sampling position of the phase-separated binder. The top section of the phase-separated binder was found to have greater rut and thermal crack resistance due to waste plastic accumulation after phase separation processes. According to storage stability data results, the phase separation issues with wet process modification can be solved with additional modifiers. However, this adds to the cost of the binder and limits the use of waste plastic in asphalt mixtures. An obvious way to circumvent the storage stability issues is to incorporate plastics by the dry process method.
The effects of 6-weeks of resistance training on the gut microbiome in young adults with overweight and obesity

Published: May 2023

[EMBARGOED UNTIL 12/1/2023] INTRODUCTION: Obesity is a known risk factor for the development of insulin resistance, type 2 diabetes, and other cardiometabolic outcomes. Recently, the gut microbiome had been identified as a possible contributor to the onset of obesity and subsequent health complications. Exercise has been regularly utilized as a therapeutic intervention to treat obesity and its associated comorbidities and has also recently been shown to have an effect on the gut microbiome. Various modalities of exercise and their effects on the gut microbiome have been studied to differing degrees, with aerobic exercise being the most commonly studied exercise modality and resistance training (RT) being the least studied modality. AIMS: Hence, we sought to examine the effects of RT on the gut microbiome (Aim 1), hypothesizing that RT would have an effect on the diversity, composition, and metabolic pathways of the gut microbiome. We additionally sought to study the effects of RT on cardiometabolic outcomes and the associations of the gut microbiome with cardiometabolic outcomes (Aim 2), hypothesizing that beneficial changes in the gut microbiome would be positively associated with changes in cardiometabolic outcomes. METHODS: Sedentary young adults (age 18-35 years) with overweight and obesity (BMI 25-45 kg/m2) were recruited to participate in this randomized controlled trial. Participants were randomized into 1 of 2 groups: RT (n=17) which participated in a 6-week resistance training program (3 days/week), or control (CT) (n=16) which continued normal patterns of daily living and served as a non-exercising control. Main outcomes of the study included gut microbiome measures (composition, diversity, and pathways) and cardiometabolic measures (glucoregulatory and cardiovascular outcomes). Data was collected at baseline (BL) and at the end of the 6-week study (W6). RESULTS: Notable findings include an increase in Roseburia genus abundance, a SCFA producer, and microbial starch and sucrose metabolism pathway abundance over 6 weeks with RT in comparison to CT (group x week, p[less than]0.05, q[less than]0.25). Moreover, RT resulted in higher QUICKI and lower diastolic blood pressure at W6 compared to CT (BL-adjusted p[less than]0.05). Correlation analyses demonstrate a trend for a moderately positive correlation of Roseburia with QUICKI (r=0.48, p[less than]0.1) and negative correlation with HOMA-IR (r=-0.46, p[less than]0.1) in the RT group at W6 which was not observed in the CT group. CONCLUSION: This study provides preliminary evidence that resistance training induces positive changes in the gut microbiome and cardiometabolic health. Additionally, the microbiome-glucoregulation associations indicate that SCFA producers may be potentially associated with glucoregulatory improvements which could have important clinical implications and should be examined in future studies with larger sample sizes.
Development of selective fluorescence neurosensor for neurotransmitter monitoring in live cells
Authors:   , Tajali Ramin
Published: May 2023

[EMBARGOED UNTIL 12/1/2023] In the central nervous system, neurotransmitters are responsible for transferring signals from pre-synaptic vesicles to post-synaptic receptors. The most abundant amino acid in brain, glutamate, is a primary excitatory neurotransmitter which plays a major role in regulating many functions in human body such as memory, learning, and long-term depression. Fluorescence approaches as a noninvasive tool provides high spatial resolution in compared with other conventional methods for neurotransmitter detection. Over the last few years, various optical probes have been reported for neurotransmitters sensing, however, they usually suffer from lack of selectivity. In this work, we plan to develop a turn on fluorescence sensor based on coumarin-3- aldehyde scaffold to selectively recognize gamma-amino acids neurotransmitters like glutamate and GABA in live cells. This neurosensor binds to the analyte through formation an iminium ion and a boronate ester. In this sensor, the distance between aldehyde functional group and boronic acid group can only fit larger gamma-amino acids over other alpha-amino acids.
Functional medicine in cancer survivors with obesity
Authors:   Korean Institute for Functional Medicine, Jung Susie
Published: May 2023

Obesity in cancer survivors has a complex problem and is influenced by many psychological, social, and biological factors. Management of these factors is important to prevent recurrent cancer, secondary cancer, and other cardiovascular disease complications while improving cancer survivors’ quality of life, such as fatigue and pain. Factors of functional medicine in obesity in cancer survivors include excessive fat accumulation, low-grade chronic inflammation, excessive estrogen in estrogen-related cancer, intestinal dysbiosis and changes in the intestinal environment, changes in cellular energy metabolism and antioxidant capacity, vital hormones, autonomic nervous system, and immune system imbalance, etc. We need to change the fundamental living environment and implement individual nutritional treatment with functional medicine approach for each patient, rather than simply satisfying the goal of weight loss for obesity in cancer survivors. In this review, the management of obese cancer survivors was discussed from four perspectives (inflammation by adipose tissue and related hormones, influence of gut microbiome, cell metabolism, antioxidant system, and immune function) based on the 7-core imbalance theories of functional medicine.
Clark H. Pinnock's Shift in His Doctrine of Biblical Authority and Reliability, an Analysis and Critique
Authors:   ,   Andrews University, Roennfeldt Ray
Published: May 2023

This study investigates Clark H. Pinnock's shift in his doctrine of biblical authority and reliability. A brief introduction, delineating the objectives, method, and delimitations of the study, is followed by an historical survey of developments inregard to biblical authority and reliability from the sixteenth century onwards. There were few doubts regarding scriptural authority and veracity until the rise of English Deism, biblical criticism, and religious liberalism. The resulting demolition of the traditional view of Scripture was protested by Fundamentalism, then by evangelicalism. Contemporary evangelicals, however, reveal little uniformity in regard to the doctrine of Scripture. Pinnock's own role in the Southern Baptist inerrancy debates can be viewed as representative of that diversity. Chapter 2 provides an overview of Pinnock's major concerns, shaping influences, and shifts of opinion regarding apologetics, soteriology, theology proper, political theology, and Pentecostalism. His desire that evangelical theology be both conservative and contemporary is revealed in his development in all these themes. Chapters 3 and 4 focus on Pinnock's early and later thinking concerning biblical authority/reliability. The early Pinnock considered that Scripture explicitly taught the inerrancy of the original autographs. He qualified the inerrancy category by reference to the "intention" of the text, regarded biblical difficulties as "apparent," and argued from biblical reliability to authority. The later Pinnock attempts to move conservatives toward acceptance of Scripture's human form. He rejects his earlier view as inadequate from the standpoint of biblical teaching and the role of the Spirit. A strict view of inerrancy is now considered incompatible with anything less than a deterministic doctrine of God. The final chapter evaluates the strengths, weaknesses, and consistency of Pinnock's two views and suggests the reason/s for his shift. While the early Pinnock stresses the divine role in inscripturation, the later seems to emphasize the human. His conclusions in each of these periods reflect his presuppositions. Pinnock's change of perspective is probably the consequence of a Calvinism to Arminianism paradigm shift which began with his soteriology, moved to his doctrine of God, and filtered into his view of Scripture. He may need to make adjustments to his system to maintain a high view of biblical authority and reliability.
Classroom Implementation of Cooperative Learning: Qualitative Case Studies of Three Early Elementary Teachers
Authors:   ,   Andrews University, Bassett W. Philip
Published: May 2023

This study uses qualitative methodology to look at the implementation of cooperative learning in three early elementary classrooms. The questions of interest were "What, from a teacher's point of view, happens when cooperative learning methods are implemented?" and "What happens to a cooperative learning model when it is implemented by trained teachers?" A review of the literature related to cooperative learning identifies three genres of cooperative learning and proposes a theoretical framework. A review of the literature related to qualitative research defines qualitative research in terms of philosophy, perspectives, applications to educational research, and data gathering and analysis techniques. A review of the very limited literature specifically related to the implementation of cooperative learning summarizes the findings of six studies. Based partly on the differing levels of support anticipated for them as they implemented, three early elementary teachers were selected for study from a group of 35 educators taking four days of training in cooperative learning. Case studies of these three teachers were based on data gathered over eight months through participant observation and ethnographic interviews. The case studies begin with a description of the teacher and narrative description of a cooperative lesson conducted by the teacher. The remainder of each case study is organized around four major categories seen in the data: (1) configuration, (2) problems, (3) implementation, and (4) teacher thinking. A cross-case analysis follows the case studies and includes summaries, conclusions, and recommendations related to teacher training, implementation, and further research. Among the findings: (1) Classroom configuration and the training model differed in social skill instruction, group processing, and the use of group contingencies. (2) A four-step model is suggested for teachers learning to use cooperative groups. (3) Problems specifically related to the use of cooperative groups were seen as less important than other problems. (4) The resolution of grouping issues is an important part of implementation. (5) Further research on teacher thinking during various stages of the implementation process may be valuable. (6) None of the three teachers received support as they sought to implement cooperative learning. Neither the principal nor collegial support groups provided any formal or informal support to the teachers even though this sort of support was anticipated at two of the schools.
