Moderating Role of Community Participation on Performance of Affordable Housing Program in Kenya

It is estimated that the current affordable housing deficit stands at 2 million houses with nearly 61% of urban households living in slums. This deficit continues to rise due to fundamental constraints on both the demand and supply side and is exacerbated by an urbanization rate of 4.2%, equivalent to 0.5 million new city dwellers every year. The study intended to examine how project management triple constraints and performance of affordable housing program in Kenya. Specifically, the study aimed to examine how project scope management and project time and moderating influence of community participation on affordable housing program in Kenya. The study was based on the theory of triple constraints and complexity theory. The study intended to adopt descriptive research design. The target population of this study was 24,000 social housing projects. The study used simple random sampling to select 393 social housing projects units from the target population.
Supplementary Materials of Online Pseudo Label Generation by Hierarchical Cluster Dynamics for Adaptive Person Re-identiﬁcation

Algorithm 1 summarizes the pseudo label generation of our framework. Training procedure of our approach on domain adaptive person ReID and unsupervised person ReID are presented in Algorithm 2 and Algorithm 3, respectively. Both tasks adopt the same pseudo label generation strategy. The only difference between the training process of domain adaptive person ReID and unsupervised person ReID is whether wk is included in Eq. 1. For adaptive ReID, there are prototypes of the source domain, i.e., wk, but there are no prototypes of the source domain in unsupervised person ReID.
Finite Element Model of Smart Beams with Distributed Piezoelectric Actuators

In the present work, the static and the dynamic analysis of intelligent advanced beams structures with piezoelectric actuators have been studied. The structure substrate is made of isotropic and/or anisotropic materials, subjected to axial and transverse mechanical loads as well as electrical load. The actuators’ layers are made of piezoelectric material of PZT type. The model is able to solve the structure with piezoelectric actuators either patches or completely covers the structure; in the upper or lower surface or impeded in the structure. The classical laminate theory is used to represent the deformation of the lamination for each considered structure. The ID isoperimetric Hermit cubic shape functions and the Lagrange interpolation functions are used to formulate the finite element model for the distributed coupled electromechanical behavior. The equations of motion of each structure system is obtained by using the principle of total potential energy considering the Euler-Bernoulli beam assumptions. A Matlab code is prepared to perform the analysis of such beams. The results of the proposed finite element model for each structure are compared to the available finite element and analytical results of other investigators, good agreement is generally obtained.
Emergence of Stereotypes Under Group Competition

How and why do racial stereotypes arise, and how do negative stereotypes harm the stereotyped group? I study a model of stereotypes as motivated reasoning when social groups interact. Even though group differences are intrinsically meaningless, agents develop ‘racial’ beliefs where they think these differences mark differences in ability when there are sufficient incentives to stereotype. These beliefs lead to asymmetric equilibria with biased first-order and higher-order beliefs, where one group chooses to denigrate the other to achieve a competitive advantage, while believing that this other group ‘sees us as we see ourselves. ’ Furthermore, stereotypes arise from competitive incentives despite the absence of ‘inherent’ animosity between groups.

Photoluminescence enhancement in multilayered MoSe2 nanostructures obtained by local anodic oxidation

Monolayers of transition metal dichalcogenides (TMDCs) exhibit attractive properties and are promising for fabricating photonic and optoelectronic devices, while bulk multilayered structures based on the same materials only recently has revealed many properties useful for nanophotonics. In this regard, the combination of monolayer and multilayer properties in one device (on a single flake) is an important and fruitful task that needs to be solved. In this work, we demonstrate the use of local anodic oxidation to improve the optical properties of multilayer MoSe2 flakes on a gold-covered substrate. Using this method, we fabricated nanostructures demonstrating extraordinarily enhanced photoluminescence (PL), with an intensity up to three orders of magnitude compared to that of the original structure. Low-frequency Raman spectroscopy showed that the nature of this PL enhancement is that the bindings between the layers inside the nanostructures are severely disrupted. This means that the nanostructures consist of quasi-monolayers, which is in good agreement with the intensity and the position of PL peak. Here, we also propose a mechanism of forming these quasi-monolayers. Therefore, this method allows using multilayer TMDC flakes on a conductive substrate to fabricate areas with quasi-monolayer optical properties, exhibiting an enhanced PL intensity.
Notes about symmetric m-adic complexity of generalized cyclotomic sequences of order two with period pq

In this paper, we consider binary generalized cyclotomic sequences with period pq, where p and q are two distinct odd primes. These sequences derive from generalized cyclotomic classes of order two modulo pq. We investigate the generalized binary cyclotomic sequences as the sequences over the ring of integers modulo m for a positive integer m and study m-adic complexity of sequences. We show that they have high symmetric m-adic complexity. Our results generalize well-known statements about 2-adic complexity of these sequences.
Numerical investigation of airfoil self-noise reduction by addition of trailing edge serrations

DNS of the flow around a NACA-0012 airfoil are conducted, employing an immersed boundary method to represent flat-plate trailing-edge extensions both with and without serrations. Properties of the turbulent boundary layer convecting over the trailing-edge are similar for all cases. For cases with serrations, the trailing-edge noise produced by the flow over the airfoil is observed to decrease in amplitude, and the frequency interval over which the noise reduction occurs differs depending on the serration length. The trailingedge noise appears otherwise largely unaffected by the serrations in terms of its directivity and spanwise coherence. The hydrodynamic behaviour in the vicinity of the trailing-edge extensions is investigated. The streamwise discontinuity imparted upon the turbulent flow by the straight trailing-edge can clearly be observed in statistical quantities, whereas for the serrated case no spanwise-homogeneous discontinuities are observed. The turbulent flow through the serrations promotes the development of horshoe vortices originating at the serrations themselves, which appear to promote a more rapid mixing within the airfoil wake.
Morbidity and long-term survival in patients with cervical re-exploration for papillary thyroid carcinoma

Abstract Background Papillary thyroid carcinoma (PTC) has a favorable prognosis following one-stage surgical therapy, whereas two-stage resections bear the risk of increased morbidity and possibly impaired prognosis. To further elucidate the value of surgical re-exploration in PTC, a retrospective study was performed. Methods The study involved 187 patients with PTC who underwent total thyroidectomy with central lymph node dissection between 2001 and 2011. The number of two-stage surgeries, the rates of recurrent laryngeal nerve paralysis (RLNP) as well as hypocalcemia, and the long-term survival were assessed. Results Two-stage surgeries were performed in 43%. No statistically significant difference was seen between the one- and two-stage resection groups regarding the rate of RLNP (transient 5.6% vs. 6.3%, permanent 2.6% vs. 0%) nor for hypocalcemia (transient 25.2% vs. 18.8%, permanent 14.0% vs. 22.5%). The 10-year recurrence-free survival was 95.5% and the 10-year disease-specific survival was 98.9% with no difference between groups. Conclusion Even though two-stage surgeries do not lead to a higher incidence of RLNP and hypocalcemia, optimal preoperative and intraoperative diagnostics have to be carried out to reduce the amount of completion surgeries.
In vitro investigation of anti-cancer activity of propolis on hepatocellular carcinoma cells

The aim of the current study is to investigate the anti-cancer activity of propolis on liver cancer, with a mechanistic approach. Ethanol extract of the collected propolis was prepared using maceration technique and anti-cancer activity of the extract was investigated on liver hepatocellular carcinoma cells (HepG2 and Hep3B cells) by focusing on viability, intracellular ROS level, total antioxidant status and apoptosis through caspase-3 activity. Total flavonoid content, total phenolic content and ferric reducing antioxidant potential values of the propolis were determined as 505.12±10.08 (mg QE/g), 308.72±5.33 (mg GAE/g) and 247.64±7.27 (mg Tro/g), respectively. Ethanol extract of the propolis induced statistically significant (p < 0.01) decreases in viability of hepatocellular carcinoma cells, HepG2 and Hep3B cells, as evidenced by IC50 values (e.g. IC 50 values of 72 h treated HepG2 and Hep3B cells were 25.62±1.50 and 31.74±2.72 μg/mL, respectively). These powerful cytotoxic effects are caused by statistically significant (p < 0.01) decrease in intracellular ROS level by natural antioxidants such as flavonoids and phenolic acids, as well as statistically significant (p < 0.01) increase in apoptosis induced by caspase-3 activity. These results suggest the great potential of propolis as a potent anti-tumor compound in liver cancer treatment for further researches.
Study of signage design and information content for The Namtok Sai Khao National Park

The Namtok Sai Khao National Park is one of the well-recognized national parks in Thailand’s southern region, accommodating both Thai and foreign visitors. Therefore, providing accurate and adequate information is essential to tourists and will enhance their travel experience. Signage is an essential tool to communicate information, rules and even reflect the appearance of the park. Data was gathered using two main methods: 1) visual content analysis of existing park signage; and, 2) and an on-site survey aimed at assessing user experience. Analysis of this data served as the basis for the development of a set of design guidelines aimed at improving the signage by restructuring the graphic elements and system and including greater support for foreign language visitors.

An evaluation of indoor thermal environment in fisherman housing in West Sumatera

Pesisir Selatan is one of the districts in West Sumatra with a humid tropical climate with temperatures reaching 32°C during the day. The majority of coastal communities work as fishermen and build houses on the beach, such as in fishermen’s housing in South Painan. In this area there are two models of fisherman housing, namely government-assisted fisherman housing and fisherman’s original housing. Housing on the beachfront will be faced with quite extreme climatic conditions such as air velocity, air temperature, and air humidity which are relatively high on average. Therefore, it is necessary to evaluate the level of thermal comfort in the space in both models of fisherman housing to determine the performance of each fisherman’s housing in dealing with the climate. This study uses a quantitative approach by measuring the parameters of thermal comfort, namely air temperature, humidity and air velocity using a thermohygrometer and anemometer. The data collection method uses descriptive quantitative. Comfort level is evaluated based on the Indonesian national standard (SNI 03-6572-2001) and adaptive thermal comfort. Based on the results of the study, the level of thermal comfort in both models of fisherman housing is classified as uncomfortable according to SNI 03-6572-2001 and adaptive thermal comfort.
Factors That Lead to Misbehaviour in Class According to Students’ Perception at UiTM Seremban 3 Using Multiple Linear Regression (MLR) Analysis

This study was conducted to describe the factors that lead to misbehaviour in class according to students’ perception in University Technology Mara (UiTM) Seremban 3. 372 students were surveyed regarding their perception of the factors that lead to misbehaviour in class. There are five factors that the researchers want to study, which are the lecturer’s personality, student’s lifestyle, influence from social media, students’ time management, and facilities. These five variables were chosen to determine the factors that lead to misbehaviour in class which is the main objective. To achieve the main objective of this study, Multiple Linear Regression (MLR) analysis will be used to come out with the result. Results show that three factors lead to misbehaviour in class. These factors are the lecturer’s personality, influence from social media and students’ time management. Other than that, there are several methods to achieve other research objectives. The Spearman correlation method was used to analyse the relationship between the factors that affect the students’ perceptions of misbehaviour in class. The analysis shows that the relationship for lecturer’s personality has a moderate positive relationship. In contrast, the other four factors, such as students’ lifestyle, influence from social media, students’ time management and facilities, have a weak positive relationship with students’ perception of misbehaviour in class. Moreover, the Kruskal Wallis test was used to identify the final objective, identifying the differences in students’ perceptions between different faculties in UiTM Seremban 3. The result shows that all students in the three faculties have the same perceptions of factors leading to misbehaviour in class. In conclusion, this study helps higher education organisations identify what makes students misbehave in class. Based on the results, organizations may know how to decrease misbehaviour cases among students. For these students, the administration needs to focus on the lecturer’s personality, influence from media social, and students’ time management in reducing the misbehaviour problem.
Actual and expected transactional and transformational leadership behaviors of project managers

In order to ensure that construction team works toward the desired objective, it is important for a project manager to behave as an effective project team leader. This paper aims to investigate actual and expected leadership of project managers by comparing the transactional and transformational leadership behavior model. To accomplish the objective, the paper first briefly reviews the ways in which leadership, especially the two models, are approached. Data were collected through a survey to 63 construction team members in several ongoing projects in Indonesia. The results indicate that the project managers frequently use both transactional and transformational behaviors in leading their team, except the laissez-faire style. Results from analytical hierarchy process analyses interestingly show that the project team members expect the project managers to exhibit transformational leadership more than transactional leadership.
Supervised and Unsupervised Data Mining Techniques on Employability of Public Higher Learning Institute Graduates in Malaysia

It is the students’ dream to secure a job right after graduation. However, there are factors that hinder their employability. This study aims to predict Malaysian graduates’ employment status based on employability factors and to profile the graduates’ satisfaction towards their curricular activities and information and communications technology (ICT) skills. A total of 375,507 student records were obtained based on tracer studies conducted by the Malaysian Ministry of Higher Education between 2015 and 2018. Due to the large amount of data with various categories, supervised and unsupervised data mining techniques were used to unmask the underlying variables and reveal hidden information about graduates’ employability for better tracing the employment status of graduates. Various types of consolidation techniques were also used to reduce the number of levels for categorical inputs in the dataset, namely, classifiers without consolidation, with manual consolidation, and with tree consolidation. Three types of data mining variable selections were used to improve the performance of the classifiers in predicting employment status. The results show that logistic regression (LR) without variable selection is the best classifier for data without consolidation, while LR using variable selection with LR stepwise is the best classifier for data with manual and tree consolidations. In profiling the satisfaction of graduates, K-Means Clustering was used, which revealed seven clusters. The most prominent cluster consisted of graduates who were highly satisfied with their ICT skills but less satisfied with their curricular activities. These data mining techniques were able to trace graduates’ employment status and identify the success factors of graduates’ employability.

Results shows that proposed second order markov model trust (SOMMT) has higher detection efficiency of malicious VM.
Electric strength of transformer oil for large electrode areas

Carefully controlled measurements of the electric strength of transformer oil are reported. Electrodes of large-diameter cylindrical geometry are used to obtain substantially uniform fields with an electrode area of up to 2m2. The results indicate the important influence of oil volume on the electric strength both for supply-frequency and 1/50? s-impulse voltages. The effects of temperature, forced oil motion and the nature of gas in solution are also studied, and it is concluded that the oil flow is an important parameter in determining the statistical distribution of breakdown measurements. The test results have been explained on the basis of gas-initiated breakdown.
Integration experiences of former Afghan refugees in Australia: What challenges have still remained after being citizens?

This paper explores, analyses, and documents the experiences of Afghan-Australians who arrived in Australia as refugees and were granted citizenship after living in Australia for several years. This research adopted a mixed method of qualitative and quantitative approaches and surveyed 102 people, interviewed 13 participants, and conducted two focus-groups within its research design. Analysis of data indicates that former Afghan refugees gradually settled down and integrated within Australian society. They value safety and security, open democracy and orderly society of Australia, as well as accessing to education and healthcare services and opportunity for social mobility. However, since the integration is a long process, they are also facing some challenges in this area. Findings of this study show that Afghan-Australians require more support from Australian governments to overcome some of these challenges particularly securing employment within their area of interests and professional occupations that they have qualifications and experiences from Afghanistan. They are also experiencing broader challenges in the area of socio-cultural issues within Australian society. Since the Afghan community is an emerging community in Western Australia, they require more support from local government to enhance their ethnic cohesion and solidarity.
Toward a Unified Model of Information Security Policy Compliance: A Conceptual Replication Study

: Moody et al. (2018) presented a unified model of information security policy compliance (UMISPC) to explain information systems security (ISS) behaviors. The model was empirically tested against 3 main types of security-related behavior: USB practices, not locking computers appropriately, and password issues. In this study, we present a conceptual replication of Moody et al. (2018) in order to provide stronger empirical support. To this end, our study has empirically examined UMISPC through three types of ISS behaviors within a work environment in the European Union (EU), where General Data Protection Regulation (GDPR) is in force. The replication of the empirical study with the three scenarios is original. While the replication in general highlights the strength of UMISPC, the results also indicate some differences from the original study and show that there is still room for improving some of its theoretical concepts.
