Effectiveness of a Proposed Program in Developing Practices and Modifying Beliefs of Practitioner Teachers About the Flipped Classroom

This study aimed to measure the effectiveness of a proposed program in developing practices and modifying beliefs of practitioner teachers about the flipped classroom. To this end, the author followed a true experimental design, wherein the experimental group received training through the proposed program, whereas the control group received none, and after the treatment the participants were invited to run a posttest. A total of 50 female students were selected randomly from the Department of Islamic Studies, Prince Sattam Bin Abdulaziz University. To measure the post-performance of the two groups, the author used an observation card and a scale of beliefs on the flipped classroom. The findings of the study revealed (a) statistically significant differences between the mean scores of the two groups on the observation card in favor of the experimental group, indicating a strong effect of the proposed program on developing the teachers’ practices of the flipped classroom; (b) statistically significant differences between the mean scores of two groups on the scale of belief in favor of the experimental group, indicating a strong effect of the proposed program on modifying teachers’ beliefs about the flipped class; and (c) a positive statistical correlation at . 05 between the teachers’ practices and beliefs about the flipped classroom.
Comparative analysis of classification techniques for network fault management

Network troubleshooting is a significant process. Many studies were conducted about it. The first step in the troubleshooting procedures is represented in collecting information. It's collected in order to identify the problems. Syslog messages which are sent by almost all network devices include a massive amount of data that concern the network problems. Based on several studies, it was found that analyzing syslog data which can be a guideline for network problems and their causes. The detection of network problems can become more efficient if the detected problems have been classified based on the network layers. Classifying syslog data requires identifying the syslog messages that describe the network problems for each layer. It also requires taking into account the formats of syslog for vendors' devices. The present study aimed to propose a method for classifying the syslog messages which identify the network problem.This classification is conducted based on the network layers. This method uses data mining instrument to classify the syslog messages. The description part of the syslog message was used for carrying out the classification process.The relevant syslog messages were identified. The features were then selected to train the classifiers. Six classification algorithms were learned; LibSVM, SMO, KNN, Naive Bayes, J48, and Random Forest. A real data set was obtained from an educational network device. This dataset was used for the prediction stage. It was found that that LibSVM outperforms other classifiers in terms of the probability rate of the classified instances where it was in the range of 89.90%-32.80%. Furthermore, the validation results indicate that the probability rate of the correctly classified instances is >70%.
Breeding success of sympatric dabbling ducks in relation to population density and food resources

Breeding success in sympatric mallard Anas platyrhynchos, teal A. crecca and wigeon A. penelope in a boreal watershed in Finland was studied for 12 years. Benthic and surface-emerging prey animals were trapped to obtain annual indices of food abundance. Mallard and teal were equally abundant over the years, being roughly twice as numerous as wigeon. Pair density, brood:pair ratio and duckling:pair ratio were used to test the hypothesis that per capita breeding success decreases in a density-dependent fashion as either pair density or the number of nesting pairs per available food unit increases. In mallard we found no density-dependent patterns at all. In teal per capita brood production decreased as prey animals became relatively scarcer, but this interpretation may not be robust. In wigeon, however, there were two independent significant patterns of direct density-dependence in a temporal succession, i.e. between pair density and per capita brood production in the early part of the breeding season, and then between per capita abundance of surface-emerging insect prey and the number of ducklings per pair. Despite wide dietary overlap and frequent co-occurrence on single lakes among species in the guild, we found no evidence for interspecific density-dependent effects. We hypothesize that there is no or infrequent food limitation for breeding dabblers in this system, and that behavior may be the process behind the pattern of density-dependence in wigeon.
Young consumer preferences of the housing environment in Makassar City

The increasing number of residents (youth) who have migrated in urban areas triggers various problems, one of which is the problem of providing housing. This study aims to look at the preferences of young consumers towards the residential environment residing in the city of Makassar. The research approach used is a quantitative approach with the analytical method used is factor analysis to reduce several indicators in several variables such as the physical condition of housing, accessibility, facilities, infrastructure, and social environment around the housing into a set of indicators that represent the preferences of young consumers.

Reply to Comment by Lynn et al. on “A Study of the F2 Layer Stratification on Ionograms Using a Simple Model of TIDs”

This paper is a response to the comment by Lynn et al. (2020, https://doi.org/10.1029/2019JA027575) on the paper by Jiang, Yang, et al. (2019, https://doi.org/10.1029/2018JA026040). Although we disagree with Lynn et al. (2020), nevertheless, we do thank them for their comments, since they have given us the opportunity to revisit and clarify some points. In Jiang, Yang, et al. (2019, https://doi.org/10.1029/2018JA026040) and this reply, we found that the F2 layer stratification induced by gravity waves/TIDs can last for about 40 min. The shape of the F2 layer stratification is similar to the F3 layer referred to by Lynn et al. (2020). However, the evolution of the F2 layer stratification by Jiang, Yang, et al. (2019, https://doi.org/10.1029/2018JA026040) is different from the F3 layer referred to in the comment by Lynn et al. (2020).
Migration of green (Chelonia mydas) and loggerhead (Caretta caretta) turtles to and from eastern Australian rookeries

Feeding-ground captures of green (Chelonia mydas) and loggerhead (Caretta caretta) turtles tagged while nesting at eastern Australian rookeries over a 21-year period are summarised. These turtles which nest in the Great Barrier Reef region range widely throughout the Arafura and Coral seas. The tag recoveries include many from turtles that live in neighbouring countries and migrate to breed in Australia. The breeding female shows a high fidelity to her home feeding ground as well as to her nesting beach. Most recaptures of the green turtles occurred during hunting for food by indigenous people while most recaptures of loggerhead turtles were incidental captures in commercial fishing activities. Migratory behaviour, imprinting and navigation are discussed.
COVID-19: potential effects on Chinese citizens’ lifestyle and travel

Purpose The 2019 novel coronavirus (COVID-19) outbreak is projected to have adverse consequences on the global tourism and hospitality industry. This paper aims to examine how the outbreak may alter Chinese tourists’ lifestyle choices, travel behaviour and tourism preferences in the short and long term. Design/methodology/approach This paper is based on the synthesis of news broadcasted by several media outlets to be supported by an overview of the related literature on tourism marketing, tourism management and tourist behaviour. The authors’ experiences investigating trends in tourism and hospitality at the local and international level have also contributed to the study. Findings This paper predicts that COVID-19 will likely affect Chinese travellers’ consumption patterns, such as the growing popularity of free and independent travel, luxury trips and health and wellness tourism. New forms of tourism including slow tourism and smart tourism may also drive future tourism activities. Such changes are likely to force businesses to reconsider their service designs and distribution channels. Research limitations/implications While Chinese and other potential visitors rethink how they travel, professionals, too, should reflect upon how to bring positive or negative changes to the tourism industry following this pandemic. Subsequent research should also consider how to mitigate the effects of similar public health crises in the future. Practical implications Recommendations for industry practitioners and policymakers focus on tailoring travel arrangements to tourists’ backgrounds. The suggestions may help to alleviate outbreak-related stress, offer travellers newly enriching experiences and partially mitigate the effects of COVID-19 on the tourism and hospitality industry. These recommendations can also apply more broadly to global tourist markets. Social implications The COVID-19 outbreak has already brought significant impacts to nearly every society and industry. Tourism scholars and practitioners should carefully consider this tragedy and how it may inform industry and social practices. This and other public health crises represent sterling opportunities to view the industry holistically in terms of its effects on the environment, climate and travellers themselves. Originality/value This paper presumably represents a frontier study, critically examining the possible impacts of COVID-19 on Chinese travellers’ consumption patterns and how the tourism and hospitality industry may respond to such changes in the future.
Protein Kinase C (cid:1) Regulates Apoptosis via Activation of STAT1*

ProteinkinaseC (cid:1) (PKC (cid:1) )isrequiredformitochondria-dependent apoptosis; however, little is known about downstream effectors of PKC (cid:1) in apoptotic cells. Here we show that activation of STAT1 is an early response to DNA damage and that STAT1 activation requires PKC (cid:1) . Treatment of HeLa cells with etoposide results in phosphorylation of STAT1 on Ser 727 and the association of STAT1 with PKC (cid:1) . Etoposide increases transcription from STAT1-dependent reporter constructs. Increased transcription, as well as STAT1 Ser 727 phosphorylation, can be blocked by inhibition or depletion of PKC (cid:1) . To ask if STAT1 is required for PKC (cid:1) -mediated apoptosis, we utilized U3A STAT1-deficient cells. Induction of apoptosis by PKC (cid:1) is suppressed in U3A cells but can be rescued by co-transfection with STAT1 (cid:2) but not STAT1 mutated at Ser 727 . Nuclear accumulation of STAT1, phospho-Ser 727 STAT1, and PKC (cid:1) are detectable 30–60 min after treatment with etoposide. Nuclear localization is necessary for apoptosis, since a nuclear localization mutant of PKC (cid:1) does not induce apoptosis in U3A cells reconstituted with STAT1 (cid:2) , and a nuclear localization mutant of Immunoblot analysis was done as previously described using 50 or 100 (cid:4) g of protein (5). For immunoprecipitation, 0.5 or 1 mg of protein was mixed with the appropriate antibody overnight, and the antigen-antibody complexes were recovered by incubation with Sepharose-protein A (Sigma) for 1–4 h at 4 °C. The beads were washed three times in MSLB buffer, and the precipitated proteins were resolved on a 10% SDS-polyacrylamide gel. Plasmid Constructs— Generation of mouse pGFPPKC (cid:1) and pGFPNLMFL8 (cid:1) has been previously described (12). The plasmids pSTAT1 (cid:3) (ST1 (cid:3) ) and pSTAT1 (cid:3) S727A (ST1 (cid:3) S727A) were obtained from Dr. James Darnell (Rockefeller (23). The plasmids pGFPST- AT1 (cid:3) (ST1 (cid:3) ) and pGFPST1 (cid:3) L407A (L407A) were obtained from Dr. Nancy Reich (SUNY (22). The interferon stimulatory re- sponse element (ISRE) and GAS cis-reporting systems and the pCIS-CK negative control plasmid were purchased from Stratagene. To generate the PKC (cid:1) -specific siRNA, pRETRO-SUPER (37) was digested with BglII/HindIII and ligated to the double-stranded oligonucleotide
Developmental Constraints and Evolution: A Perspective from the Mountain Lake Conference on Development and Evolution

Developmental constraints (defined as biases on the production of variant phenotypes or limitations on phenotypic variability caused by the structure, character, composition, or dynamics of the developmental system) undoubtedly play a significant role in evolution. Yet there is little agreement on their importance as compared with selection, drift, and other such factors in shaping evolutionary history. This review distinguishes between "universal" and "local" constraints; it deals primarily with the latter, which apply to a limited range of taxa. Such constraints, typically, can be broken even within the taxa to which they apply, though with varying degrees of difficulty. The origin of constraints is discussed, five distinctive of constraint being explicitly considered. Three means of identifying constraints are set forth, as well as four means of distinguishing developmental from selective constraints. None of the latter (use of a priori adaptive predictions, direct measurement of selection, direct measurement of heritable variation, and use of the comparative method) is foolproof. In the final section, three larger issues regarding the role of developmental constraints in evolution are discussed: the extent to which evolutionary stasis can be explained in developmental terms, the extend to which evolutionary trends and patterns might be a consequence of developmental constraints, and the extent to which various genetic and developmental mechanisms have evolved in virtue of the need of lineages to manifest evolutionary plasticity (or adaptability) if they are to survive. Although no definitive conclusions are reached on these larger issues, we bring recent advances in developmental biology, evolutionary theory, and (to a limited extent) molecular biology to bear on them.
Structural features that affect the binding of teicoplanin, ristocetin A, and their derivatives to the bacterial cell-wall model N-acetyl-D-alanyl-D-alanine

Studies with the title antibiotics have confirmed that the N-terminal amino groups of such glycopeptides play a major role in binding to N-acetylD-alanyl-D-alanine; one sugar is found to affect free energy of binding but the other sugars and fatty acid groups attached to the aglycones have more uncertain roles.
Fotovoltaik Sistemlerde Maksimum Güç Noktası Takibinde Kullanılan Algoritmaların Kısmi Gölgeleme Koşulları Altında Karşılaştırılması

In order to increase efficiency in photovoltaic systems (PV), maximum power point tracking (MPPT) is performed with the help of power electronic converters. While MPPT is performed in uniformly distributed radiation conditions, one of the traditional algorithms, perturb and observe (P&O) algorithm is very efficient. However, when partial shading conditions occur, this algorithm cannot find global maximum power points and caught to local maximum power points. In contrast, nature inspired metaheuristic algorithms such as particle swarm optimization (PSO) and cuckoo search optimization (CSO) algorithm are more successful in finding the global maximum. In this study, a system consisting of photovoltaic array, DC-DC boost converter and load has been developed in MATLAB/SIMULINK. Using this system, MPPT was performed with P&O, PSO and CSO algorithms under partial shading conditions and comparative analysis of these algorithms was performed. These algorithms were compared with three different partial shading configurations for tracking time and accuracy. As a result of the simulations, the P&O algorithm caught to a local point, while the PSO and CSO algorithms were successful in finding the global point. When PSO and GKO algorithm are compared, it is seen that CSO algorithm reaches global point faster than PSO algorithm.
Photosynthesis and nutrient supply in needles of Sitka spruce [Picea sitchensis (Bong.) Carr.].

Growth and photosynthetic development were measured for currently developing needles of young trees of Sitka spruce [Picea sitchensis (Bong.) Carr. ] throughout their fourth growth season. Treatments included trees that were fully fertilized (control), trees deficient in phosphorus (-P), or nitrogen (-N), and trees initially deficient but then supplied with phosphorus (-PR) or nitrogen (-NR). Growth was measured in terms of needle projected area, and the photosynthetic components measured were pigment concentration, net photosynthetic rate, (PN ), activity of ribulose-1,5-bisphosphate carboxylase, (RuBPC), stomatal conductance to CO2 , (Gs ), and the intercellular partial pressure of CO2 , (Ci ). Needle growth was rapid, beginning in early May and being complete by the end of the month or early in June. Free growth occurred in the -NR treatment. Photosynthesis increased throughout the season, reaching a peak in August, with some variables subsequently showing a decrease in value. PN increased more rapidly during needle expansion than either chlorophyll concentration or RuBPC activity. Phosphorus deficiency led to a reduction in RuBPC activity, which was restored to the control value following Refertilization with P. Nitrogen deficiency severely reduced values of all variables studied, except Ci , which was higher than for the controls. Refertilization of -N trees caused a very rapid increase in values of all variables, with an increase in Ci , representing a larger increase in mesophyll conductance to CO2 , (GM ), than GS , PN and RuBPC activity were significantly correlated with total chlorophyll concentration for all treatments, but PN was not correlated with GS or RuBPC activity.
Work Integrated Learning at Tertiary Level to Enhance Graduate Employability in Bangladesh

In the last few years, higher education institutions (HEIs) in Bangladesh have been under severe pressure to transform the way they operate. The present Government of Bangladesh requires all universities to improve their quality of education and has implemented various projects such as Higher Education Quality Enhancement Project (HEQEP) in collaboration with the World Bank. As Bangladesh has set a target to transition out of the status of Least Developed Country (LDC) to Developing country by 2024, graduate employability and education quality are pivotal interests for the Government of Bangladesh. This paper investigates the concept of work integrated learning (WIL) and generic skills vital to enhance the employability of the current graduates in Bangladesh. We explore different types of WIL that can be applied at higher academic institutions in Bangladesh and what are the various benefits of this type of learning to the key stakeholders, namely; students, universities and employers. Finally, we conclude by pointing out the prerequisites that need to be considered in order to successfully implement WIL in Bangladesh. This is a descriptive study and we have collected data from different secondary sources such as documents available from government agencies, research organizations, archives and library. Moreover, we have also used interviews from sources such as newspapers and magazines documenting views of well-respected academicians and personalities in Bangladesh. Our findings indicate that in order to successfully integrate WIL, there are some prerequisites such as modifying the current curriculum, designing and offering work oriented courses, building strong connections with potential employers and creating awareness about WIL among faculty members and students.
Risk Management for Bonds with Embedded Options

This paper examines the behavior of the interest rate risk management measures for bonds with embedded options and studies factors it depends on. The contingent option exercise implies that both the pricing and the risk management of bonds requires modelling future interest rates. We use the Ho and Lee (HL) and Black, Derman, and Toy (BDT) consistent interest rate models. In addition, specific interest rate measures that consider the contingent cash-flow structure of these coupon-bearing bonds must be computed. In our empirical analysis, we obtained evidence that effective duration and effective convexity depend primarily on the level of the forward interest rate and volatility. In addition, the higher the interest rate change and the lower the volatility, the greater the differences in pricing of these bonds when using the HL or BDT models.
