Since the turn of the 21st century, the emporium model has become a popular choice for colleges and universities to reform developmental mathematics. The purpose of this study is to determine overall how successful Northeast Metro College (NMC)’s emporium developmental mathematics program is as compared to its traditional lecture-based program by comparing these two programs’ student pass rates in developmental courses. This research is a non-experimental, secondary data quantitative analysis study with nonrandom convenience samples. The findings indicate that generally emporium classes prepare students for passing developmental mathematics more successfully than traditional lecture-based classes do.
Solving Course Selection Problem by a Combination of Correlation Analysis and...IJECEIAES
In the universities where students have a chance to select and enroll in a particular course, they require special support to avoid the wrong combination of courses that might lead to delay their study. Analysis shows that the students' selection is mainly influenced by list of factors which we categorized them into three groups of concern: course factors, social factors, and individual factors. This paper proposed a two-phased model where the most correlated courses are generated and prioritized based on the student preferences. At this end, we have applied the multi-criteria analytic hierarchy process (MC-AHP) in order to generate the optimum set of courses from the available courses pool. To validate the model, we applied it to the data from students of the Information System Department at Taibah University, Kingdom of Saudi Arabia.

The purpose of the study is to determine the effectiveness of the metacognitive strategies as instructional approaches in teaching and learning of Basic Calculus. A number of 48 students consisting of 24 boys and 24 girls were purposively sampled in this study. Pretest-posttest quasi experimental research design was used which applied t-test and descriptive statistics. Both groups were subject to two instruments that were comprised of problem-solving test (pretest and posttest) and observation guide. Experimental group was taught Basic Calculus using metacognitive strategies while the control group was taught Basic Calculus using traditional teaching strategies. Both groups were subject to a pretest. Class observation was done while the two teaching strategies were applied. In the end, the posttest was administered to both groups to identify the effectiveness of the two teaching strategies. The data gathered were treated using paired sample t-test and independent sample t-test. The results of the study showed that the experimental group had significantly higher posttest scores as compared to control group which proved that metacognitive teaching strategies were more effective in improving the performance and problem-solving skills of the students than the traditional teaching strategies. It was also observed that students who taught using metacognitive strategies helped the students to be extremely engaged in Basic Calculus lessons cognitively, behaviorally, and affectively. The study reveals that the significant increase of the students’ learning engagement in Basic Calculus lessons led the students to a corresponding increase in their posttest scores.

The current production for energy consumption generates harmful impacts of carbon dioxide to the environment causing instability to sustainable development goals. The constitutional reforms of British Government serve to be an important means of resolving any encountered incompatibilities to political environment. This study aims to evaluate green economy using developed equation for renewable energy towards political polarization of corporate governance. The Kano Model Assessment is used to measure the equivalency of 1970 Patents Act to UK Intellectual Property tabulating the criteria for the fulfillment of sustainable development goals in respect to the environment, artificial intelligence, and dynamic dichotomy of administrative agencies and presidential restriction, as statutory interpretation development to renewable energy. The constitutional forms of British government satisfy the sustainable development goals needed to fight climate change, advocate healthy ecosystem, promote leadership of magnates, and delegate responsibilities towards green economy. The presidential partisanship must be observed to delineate parties of concerns and execute the government prescriptions in equivalence to the dichotomous relationship of technology and the environment in fulfilling the rights and privileges of all citizens. Hence, the political elites can execute corporate governance towards sustainable development of renewable energy promoting environmental parks and zero emission target of carbon dioxide discharges. The economic theory developed in statutory interpretation for renewable energy serves as a tool to reduce detrimental impacts of carbon dioxide to the environment, mitigate climate change, and produce artefacts of bioenergy and artificial intelligence promoting sustainable development. It is suggested to explore other vulnerabilities of artificial intelligence to prosper economic success.

Analysis of Value Chain of Cow Milk: The Case of Itang Special Woreda, Gambel...AI Publications
Ethiopia has a long and rich history of dairy farming, which was mostly carried out by small and marginal farmers who raised cattle, camels, goats, and sheep, among other species, for milk. Finding the Itang Special Woreda cow milk value chain is the study's main goal. In order to gather primary data, 204 smallholder dairy farmer households were randomly selected, and the market concentration ratio was calculated using 20 traders. Descriptive statistics, econometric models, and rank analysis were used to achieve the above specified goals. Out of all the participants in the milk value chain, producers, cafés, hotels, and dairy cooperatives had the largest gross marketing margins, accounting for 100% of the consumer price in channels I and II, 55% in channels III and V, and 25.5% in channels V. The number of children under five, the number of milking cows owned, the amount of money from non-dairy sources, the frequency of extension service contacts, the amount of milk produced each day, and the availability of market information were found to have an impact on smallholders' involvement in the milk market. Numerous obstacles also limited the amount of milk produced and marketed. The poll claims that general health issues, sickness, predators, and a lack of veterinary care are plaguing farmers. In order to address the issue of milk perishability, the researchers recommended the host community and organization to construct an agro milk processor, renovate the dairy cooperative in the study region, and restructure the current conventional marketing to lower the transaction and cost of milk marketing.
Minds and Machines: Impact of Emotional Intelligence on Investment Decisions ...AI Publications
In the evolving landscape of financial decision-making, this study delves into the intricate relationships among Emotional Intelligence (EI), Artificial Intelligence (AI), and Investment Decisions (ID). By scrutinizing the direct influence of human emotional intelligence on investment choices and elucidating the mediating role of AI in this process, our research seeks to unravel the complex interplay between minds and machines. Through empirical analysis, we reveal that EI not only directly impacts ID but also exerts its influence indirectly through AI-mediated pathways. The findings underscore the pivotal role of emotional awareness in investor decision-making, augmented by the technological capabilities of AI. It suggests that most investors are influenced by the identified emotional intelligence when making investment decisions. Furthermore, AI substantially impacts investors' decision-making process when it comes to investing; nevertheless, AI partially mediates the relationship between emotional intelligence and investment decisions. This nuanced understanding provides valuable insights for financial practitioners, policymakers, and researchers, emphasizing the need for holistic strategies that integrate emotional and technological dimensions in navigating the intricacies of modern investment landscapes. As the synergy between human intuition and artificial intelligence becomes increasingly integral to financial decision-making, this study contributes to the ongoing discourse on the symbiotic relationship between minds and machines in investments.0
Bronchopulmonary cancers are common cancers with a poor prognosis. It is the leading cause of death by cancer in Algeria and in the world. Behind this unfavorable prognosis hides numerous disparities according to age, sex, and exposure to risk factors, ranking 4th among incident cancers and developing countries including Algeria, all sexes combined. It ranks 2nd cancers in men and 3rd among women. Whatever the age observed, the incidence of this cancer is higher in men than in women, however the gap is narrowing to the detriment of the latter. The results of scientific research agree to relate trends in incidence and mortality rates to tobacco consumption, including passive smoking. Furthermore, other risk factors are mentioned such as exposure to asbestos in the workplace or to radon for the general population, or even genetic predisposition. However, the weight of these etiological and/or predisposing factors is in no way comparable to that of tobacco in the genesis of lung cancer and the resulting mortality. We provide a literature review in our article on the descriptive and analytical epidemiology of lung cancer.

The objective os this study is to present Current Changes in the Role of Agriculture and Agri-Farming Structures in Thailand and Vietnam with SLM practices. Farmer’s adoption and investment in SLM is a key for controlling land degradation, enhancing the well-being of society, and ensuring the optimal use of land resources for the benefit of present and future generations (World Bank, 2006; FAO, 2018). And agriculture remains an essential element of lives of many farmers in term of the strong cultural and symbolic values that attach current working generation to do and to spend time for it but not intern of income generating.
Growth, Yield and Economic Advantage of Onion (Allium cepa L.) Varieties in R...AI Publications
Haphazard and low soil fertility, low yielding verities and poor agronomic practices are among the major factors constraining onion production in the central rift valley of Ethiopia. Therefore, a field experiment was conducted in East Showa Zone of Adami Tulu Jido Combolcha district in central rift valley areas at ziway from October 2021 to April 2022 to identify appropriate rate of NPSB fertilizer and planting pattern of onion varieties. The experiment was laid out in split plot design of factorial arrangement in three replications. The main effect of NPSB blended fertilizer rates and varieties (red coach and red king) significantly (p<0.01) influenced plant height, leaf length, leaf diameter, leaf number and fresh leaf weight, shoot dry matter per plant, and harvest index. Total dry biomass, bulb diameter, neck diameter, average fresh bulb weight, bulb dry matter, marketable bulb yield, and total bulb yield were significantly (p<0.01) influenced only by the main effect of NPSB blended fertilizer rates. In addition, unmarketable bulb yield was statistically significantly affected (p≥0.05) by the blended fertilizer rates and planting pattern. Moreover, days to 90% maturity of onion was affected by the main factor of NPSB fertilizer rate, variety and planting pattern. The non-fertilized plants in the control treatment were inferior in all parameters except unmarketable bulb yield and harvest index. Significantly higher marketable bulb yield (41 t ha-1) and total bulb yield (41.33 t ha-1) was recorded from 300 kg ha-1 NPSB blended fertilizer rate applied. Double row planting method and hybrid red coach onion variety had also gave higher growth and yields. The study revealed that the highest net benefit of Birr, 878,894 with lest cost of Birr 148,006 by the combinations of 150 kg blended NPSB ha-1 with double row planting method (40cm*20cm*7cm) and red coach variety which can be recommendable for higher marketable bulb yield and economic return of hybrid onion for small scale farmers in the study area. Also, for resource full producers (investors), highest net benefit of Birr 1,205,372 with higher cost (159,628 Birr) by application of 300 kg NPSB ha-1 is recommended as a second option. However, the research should be replicated both in season and areas to more verify the recommendations.
Evaluation of In-vitro neuroprotective effect of Ethanolic extract of Canariu...AI Publications
The ethanolic extract of canarium solomonense leaves (ecsl) was studied for its neuroprotective activity. The neuroprotective activity of ECSL was found to have a significant impact on neuronal cell death triggered by hydrogen peroxide (MTT assay) in human SH-SY5Y neuroblastoma cells. Scopolamine, a muscarinic receptor blocker, is frequently used to induce cognitive impairment in laboratory animals. Injections of scopolamine influence multiple cognitive functions, including motor function, short-term memory, and attention. Using the Morris water maze, the Y maze, and the passive avoidance paradigm, memory enhancing activity in scopolamine-induced amnesic rats was evaluated. Using the Morris water maze, the Y maze, and the passive avoidance paradigm, ECSL was found to have a substantial effect on the memory of scopolamine- induced amnesic rats. Our experimental data indicated that ECSL can reverse scopolamine induced amnesia and assist with memory issues.
The goal of neuroprotection is to shield neurons against damage, whether that damage is caused by environmental factors, pathogens, or neurodegenerative illnesses. Inhibiting protein-based deposit buildup, oxidative stress, and neuroinflammation, as well as rectifying abnormalities of neurotransmitters like dopamine and acetylcholine, are some of the ways in which medicinal herbs have neuroprotective effects [1-3]. This review will focus on the ways in which medicinal herbs may protect neurons.

Breast hamartoma is a rare, well-circumscribed, benign lesion made up of a variable quantity of glandular, adipose and fibrous tissue. This is a lesion that can affect women at any age from puberty. With the increasingly frequent use of imaging methods such as mammography and ultrasound as well as breast biopsy, cases of hamartoma diagnosed are increasing. The diagnosis of these lesions is made by mammography. The histological and radiological aspects are variable and depend on its adipose tissue content. The identification of these lesions is important in order to avoid surgical excisions. We report radio-clinical and pathological records of breast hamartoma.
A retrospective study on ovarian cancer with a median follow-up of 36 months ...AI Publications
Ovarian cancer is relatively common but serious and has a poor prognosis. The aim of this study is to highlight the epidemiological, diagnostic, therapeutic and evolutionary aspects of this malignant pathology managed at the Bejaia university hospital center. This is a retrospective and descriptive study over a period of 3 years (2019 - 2022) carried out on 20 patients who developed ovarian cancer. The average age of the patients was 50 years old, 53.23% of whom were over 45 years old. The CA-125 blood test was positive in 18 out of 20 patients. The tumors were discovered on ultrasound in 87.10% of cases and at laparotomy in 12.90%. Total hysterectomy with bilateral adnexectomy was the most performed procedure (64.52%). The early postoperative course was simple. 15 patients underwent second look surgery (16.13%) for locoregional recurrences. Epithelial tumors were the most frequent histological type (93.55%), including 79% in the advanced stage ( IIIc -IV) and 21% in the early stage (Ia- Ib ). Adjuvant chemotherapy was administered in 80% of patients. With a median follow-up of 36 months, 2 patients were lost to follow-up. The evolution was favorable in 27.42% and in 25.81% deaths occurred late postoperatively. Ovarian cancer is not common but serious given the advanced stages and the high rate of late postoperative deaths which were largely observed in patients deprived of adequate neoadjuvant or adjuvant chemotherapy.

Cultivating Proactive Cybersecurity Culture among IT Professional to Combat E...AI Publications
In the current digital landscape, cybercriminals continually evolve their techniques to execute successful attacks on businesses, thus posing a great challenge to information technology (IT) professionals. While traditional cybersecurity approaches like layered defense and reactive security have helped IT professionals cope with traditional threats, they are ineffective in dealing with evolving cyberattacks. This paper focuses on the need for a proactive cybersecurity culture among IT professionals to enable them combat evolving threats. The paper emphasis that building a proactive security approach and culture can help among IT professionals anticipate, identify, and mitigate latent threats prior to them exploiting existing vulnerabilities. This paper also points out that as IT professionals use reactive security when dealing with traditional attacks, they can use it collaboratively with proactive security to effectively protect their networks, data, and systems and avoid heavy costs of dealing with cyberattack’s aftermaths and business recovery.
The Impacts of Viral Hepatitis on Liver Enzymes and BilrubinAI Publications
Viral hepatitis is an infection that causes liver inflammation and damage. Several different viruses cause hepatitis, including hepatitis A, B, C, D, and E. The hepatitis A and E viruses typically cause acute infections. The hepatitis B, C, and D viruses can cause acute and chronic infections. Hepatitis A causes only acute infection and typically gets better without treatment after a few weeks. The hepatitis A virus spreads through contact with an infected person’s stool. Protection by getting the hepatitis A vaccine. Hepatitis E is typically an acute infection that gets better without treatment after several weeks. Some types of hepatitis E virus are spread by drinking water contaminated by an infected person’s stool. Other types are spread by eating undercooked pork or wild game. Hepatitis B can cause acute or chronic infection. Recommendation for screening for hepatitis B in pregnant women or in those with a high chance of being infected. Protection from hepatitis B by getting the hepatitis B vaccine. Hepatitis C can cause acute or chronic infection. Doctors usually recommend one-time screening of all adults ages 18 to 79 for hepatitis C. Early diagnosis and treatment can prevent liver damage. The hepatitis D virus is unusual because it can only infect those who have a hepatitis B virus infection. A coinfection occurs when both hepatitis D and hepatitis B infections at the same time. A superinfection occurs already have chronic hepatitis B and then become infected with hepatitis D. The aim of this study is to find the effect of each type of viral hepatitis on the bilirubin (TB , DSB) , and liver enzymes; AST, ALT, ALP,GGT among viral hepatitis patients. 200 patients were selected from the viral hepatitis units in the central public health laboratory in Baghdad city, all the chosen cases were confirmed as a positive samples , they are classified into four equal group each with fifty individual and with a single serological viral hepatitis type either; anti-HAV( IgM ) , HBs Ag , anti-HCV ,or anti-HEV(IgM ). All patients were tested for; serum bilirubin ( TB ,D.SB ) , AST , ALT , ALP , GGT. Another fifty quite healthy and normal person was selected as a control group for comparison. . Liver enzymes and bilirubin changes are more pronounced in HAV, HEV than HCV and HBVAST and ALT lack some sensitivity in detecting HCV ,HBV and mild elevations of ALT or AST in asymptomatic patients can be evaluated efficiently by considering ,hepatitis B, hepatitis C. ALT is generally a more sensitive indicator of acute liver cell damage than AST, It is relatively specific for hepatocyte necrosis with a marked elevations in viral hepatitis.

Determinants of Women Empowerment in Bishoftu Town; Oromia Regional State of ...AI Publications
The purpose of this study was to determine the status of women's empowerment and its determinants using women's asset endowment and decision-making potential as indicators. To determine representative sample size, this study used a two-stage sampling technique, and 122 sample respondents were selected at random. To analyze the data in this study, descriptive statistics and a probit model were used. The average women's empowerment index was 0.41, indicating a relatively lower status of women's empowerment in the study area. According to the study's findings, only 40.9% of women were empowered, while the remaining 59.1% were not. The probit model results show that women's access to the media, women's income, and their husbands' education status have a significant and positive impact on the status of women's empowerment, while the family size of households has a negative impact. As a result, it is important to enhance women's access to the media and income, promote family planning and contraception, and improve men's educational status in order to improve the status of women's empowerment.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.

experiencing some promising outcomes from several pilot
programs aiming to improve developmental mathematics,
NMC began to implement the emporium model for all
existing developmental mathematics courses.
Simultaneously NMC is running traditional lecture-based
developmental mathematics courses. All gateway courses
are traditional lecture-based. NMC focused on self-paced
computer-based mastery method to implement the
emporium model. How does self-paced computer-based
mastery method work? After the Accuplacer test,
remediation students have their free choice to enroll in the
traditional course(s) or in the self-paced computer-based
mastery course(s). The emporium classes meet twice a
week with the same professor at a learning computer hub
center which has 48 student stations and accommodates
two class sections of 24 each with two professors and two
student tutors. After class time, students can go to a large
annex center with 24 student stations for dropping-ins and
separate testing. The annex center opens six days a week
and is staffed by at least two full-time supervisors.
Students watch videos related to each homework
assignment to begin with, complete notes related to each
video, and achieve a level of mastery on each assignment.
Students are able to work at their own pace and may retake
tests to improve their score. Knowledge and concepts are
organized into modules. Students watch video of a
particular model first and then review video notes. During
class time, professors and tutors stand by to answer on-
demand individual request for assistances. Students then
do warming-up exercises and homework and take the test
whenever they feel ready. All student computer activities
can be monitored by professors and tutors. So even if
students do not ask questions and if the monitored
computer activities indicate students are stuck in certain
assignments, professors and tutors can proactively come to
students to assist. Immediately students will receive
feedback on tests and homework. Students only will be
allowed to move to the next module if they successfully
pass the test of the current module with a score at least
70% (mastery method). Students have the opportunity to
progress more quickly (or slowly) with the help of
courseware, MyMathLab, and they gain flexible
scheduling accommodations. There are cost savings for
students in this model. Students are able to complete more
than one developmental mathematics course in one
semester if motivated. Students are able to begin the next
semester where they left off. Students can adjust schedule
to suit life changes.
What are the differences between a “self-paced”
class and a “traditional” class? The self-paced mastery
program provides students with the opportunity to go
through a course “at their own pace” instead of being
controlled by the pace of the teacher in the traditional
mathematics lecture time. In the self-paced computer labs
staffed by professors and professional and peer tutors,
students work on computer-based activities. Students
spend the bulk of their course time doing mathematics
problems rather than listening to a traditional mathematics
lecture. Advantages of the self-paced program are:
accommodates different learning styles; offers both videos
and power points; offers on-demand individual assistance;
provides immediate feedback on tests and homework;
affords the opportunity to progress more quickly and
complete two classes in one semester; and enables the
students to become independent learners.
Students are placed into relevant remedial
mathematics courses, as shown in Table 1, as per their
Accuplacer test scores which are based on 120 points.
Table 1: Accuplacer Placement
In order to enroll in a gateway mathematics course,
students must demonstrate proficiency in basic
mathematics and elementary algebra. Students may enroll
in any of the following gateway mathematics courses:
MAT101 - Contemporary Mathematics; MAT102 -
Statistics I; MAT103 - Finite Mathematics; MAT104 -
Intermediate Algebra. MAT101, MAT102, and MAT103
are general education courses. These courses may be used
to satisfy the mathematics general education requirement.
MAT104 is not a general education course and thus cannot
be used to satisfy this degree requirement.
III. METHODOLOGY
The purpose of this study is to determine overall how
successful NMC’s emporium developmental mathematics
program is as compared to its traditional lecture-based
program by comparing these two programs’ student pass
rates in developmental courses. Therefore, this study

H1. There is a statistically significant difference in
developmental mathematics pass rates for two groups:
students in the emporium classes and those in the
traditional lecture-based classes.
Type of research. Because of the availability of
existing data and no requirement of experimental
treatments, this research was a non-experimental,
secondary data quantitative analysis study with nonrandom
convenience samples. There is not a single best way to
determine an academic program’s success or failure.
However, pass rate is deemed as one of the most effective
and feasible assessment indicators. By examining the pass
rates, this study applied several statistical analyses to
validate the findings.
Population and Sample. The population were all
NMC’s developmental students (at least 18 years old at the
time of enrollment). The sample was any student who took
at least one developmental mathematics course in any of
the fall or spring semesters of 2016–17 or 2017–18.
Students could take different developmental mathematics
courses as well as repeat them during the four semesters
included in the study. Developmental mathematics courses
included DM2 - Basic Mathematics, DM3 - Accelerated
Basic Mathematics, DM4 - Algebra for Liberal Arts, DM5
- Algebra Topics, and DM6 – Algebra.
Data Collection. Final course grades of development
mathematics (DM2, DM3, DM4, DM5, and DM6) in the
fall and spring semesters of 2016 – 2017 and 2017 – 2018
were collected for NMC students (at least 18 years old at
the time of enrollment). No student identifiers were in the
data set. The enrollment data of developmental
mathematics courses in the fall and spring semesters of
2016 – 2017 and 2017 – 2018 were shown in Table 2.
Combining the four semesters, there were a total
enrollment of 8061 in developmental mathematics.
Approximately one out of four developmental mathematics
students took emporium classes.
Table 2: Developmental Math Enrollment 2016 – 2018
Data Analysis. IBM’s SPSS Statistics was used to
conduct all calculations and various data analysis. SPSS
(Statistical Package for the Social Sciences) is a software
package used for interactive and statistical analysis.
Originally developed by SPSS Inc., it was acquired by
IBM in 2009 and renamed as IBM SPSS Statistics [7].
Excel macros and functions were used to confirm the
calculations and statistical analysis done by SPSS. The
researcher calculated pass rates of developmental
mathematics of various student groups studied for fall
2016, spring 2017, fall 2017, and spring 2018. Chi-square
tests of goodness-of-fit were performed to further analyze
whether there was a significant difference in pass rates
between student groups. Because of its easiness of
construction and its reliability, the Chi-square test is
frequently used to determine whether there is a significant
difference between the expected values and the observed
values in one or more variables among groups [8]. Chi-
square (x²) with a (the level of significance) set at 0.05. If
p (possibility of occurrence) < 0.05, the researcher would
reject the null hypothesis that no significant difference is
between or among groups and thus, would confirm the
proposed hypothesis that significant difference is between
or among groups. On the other hand, if p > 0.05, the
researcher would accept the null hypothesis without
enough evidence to support the proposed hypothesis. If p =
0.05, the researcher would neither confirm nor reject the
proposed and null hypotheses. To answer R1, first the
researcher calculated the developmental mathematics pass
rate for each group in each semester: students in the
emporium classes and those in the traditional lecture-based
classes. Second a Chi-square test was used to further
analyze if there was a significant difference between the
pass rates of these two student groups in each semester.
Lastly, the researcher compared numerically the two
groups’ pass rates. H1 was then tested. If at least three of
four semesters’ ps < 0.05, the researcher would confirm
H1 and reject its null hypothesis. Otherwise, the researcher
would reject H1 and accept its null hypothesis.

Fig. 1: Developmental mathematics pass rates.
There is a difference in developmental mathematics
pass rates for two groups: students in the emporium classes
and those in the traditional lecture-based classes (see Table
3 and Figure 1). For each semester, the emporium pass rate
has been higher than the traditional pass rate. A Chi-square
test of goodness-of-fit was performed to determine
whether there was a significant difference in pass rates
between emporium and traditional students. Over the
period of two years studied, with the exception for spring
2018, all ps < 0.05 assert that there was a significant
difference in pass rates between emporium and traditional
students and that the pass rates in the two groups were
affirmatively contingent upon the type of developmental
mathematic models students enrolled. With emporium
students significantly outperforming traditional students in
three of the four semesters, the researcher confirmed H1
and rejected its null hypothesis. Developmental
mathematics pass rate for students in the emporium classes
was higher (statistically significant) than that for students
in the traditional lecture-based classes and the researcher
concluded that generally emporium classes prepared
students for passing developmental mathematics more
successfully than traditional lecture-based classes did.
V. DISCUSSIONS AND CONCLUSION
Limitations of the Study. While comparing pass
rates for the two student groups (emporium and
traditional), the study assumes that the prior mathematics
levels of emporium students and those in the traditional
students were not significantly different. There is no
guarantee for this assumption. As in any non-experimental
studies, the researcher would not be able to control,
manipulate or change part of the experiment [8]. Instead,
the researcher would rely on existing student records to
draw the conclusion. Thus, the data obtained from NMC
are assumed to be in the good state and have been verified.
To enroll in emporium developmental mathematics
courses, students had to agree with the self-paced
computer-based setting. Students might not be used to this
type of learning environment. The time period studied was
limited to two academic years because the emporium
program was only launched a few years ago. Instructors
and students might have biases (positive and/or negative)
about the emporium classes. The researcher also
acknowledges that the findings of the study may not be
conclusive for colleges of different characteristics for their
developmental mathematics populations.
RECOMMENDATIONS
Currently all gateway math courses are traditional
lectured-based. After emporium students complete
developmental courses, one would argue that they likely
prefer to enroll in emporium gateway courses. The
researcher recommends the offerings of a few emporium
sections for each gateway course as a starter. Then conduct
a research on the emporium model for both developmental
and gateway classes. The future study would find more
conclusive and convincing results.
Future Research. The current study was a
quantitative research and it is crucial to get student, staff
and faculty points of views regarding the emporium
model. A mixed-method research would produce more
insightful and comprehensive findings. The researcher
would replicate the study incorporating interviews and
surveys to get qualitative data from developmental
mathematics students, staff and faculty. The study can be
also improved by collecting and analyzing emporium
gateway student data after NMC offers emporium gateway
classes.
Conclusion. Overall, NMC has implemented a very
successful emporium developmental mathematics
program. Emporium classes prepared students for passing
developmental mathematics more effectively than
traditional lecture-based classes. The need to study the
emporium model in developmental mathematics is urgent
as more students arrive at colleges academically
underprepared in mathematics [2]. The emporium model is
rather a new and innovative instruction method applying
technologies. “One size fits all” approach does not work.
After initial implementations, each college should collect
and analyze its own data to determine if appropriate steps
are being executed and if necessary, additional operations
are to be implemented.
