Published: October 2018

Este artigo tem como objetivo avaliar se os mecanismos de governança que são formados e se de fato exercem influência sobre o valor de mercado e a rentabilidade das companhias abertas no Brasil. A pesquisa foi dividida em duas partes inter-relacionadas. A primeira parte investigou duas empresas em que a governança corporativa foi aplicada de forma incorreta, nas quais seus principais pilares, transparência, equidade, prestação de contas e responsabilidade social, não foram respeitados e com isso as consequências foram extremas, tanto do ponto de vista social como financeiro. Na outra ponta foram pesquisadas duas empresas em que a governança vem sendo aplicada de maneira incisiva, correta na organização, com práticas fomentadas não apenas com base nos pilares da governança, mas influenciados pela cultura organizacional das empresas.

New Trypanosoma cruzi Trypanothione Reductase Inhibitors Identification using the Virtual Screening in Database of Nucleus Bioassay, Biosynthesis and Ecophysiology (NuBBE)
Authors: do Carmo Santos Nelcí , da Paixão Vinícius G. , da Rocha Pita Samuel S.
Published: October 2018

Background:

American trypanosomiasis, also known as Chagas disease, is caused by
the protozoan Trypanosoma cruzi (T. cruzi) and affects approximately 10 to 12 million, primarily
in Latin America. Since its discovery in 1909, there is no effective treatment for its chronic phase,
with benzonidazole being the only anti-trypanosoma drug used in Brazil, despite the absence of
conclusive evidence to prove its efficacy and safety. Thus, it is necessary to develop new drugs that
are more effective and selective against Trypanosoma cruzi.

Methods:

The T. cruzi enzyme Trypanothione Reductase (TcTR) is a validated target for the discovery
of new antiprotozoal compounds and we employed the Virtual Screening technique on the
database of Nucleus of Bioassays, Biosynthesis and Ecophysiology (NuBBE), aiming to search for
new chemical moieties against T. cruzi. From these we selected the 10 best ligand energies interactions
and verified their interaction profile with the main TcTR sites through the AuPosSOM server
(https://www.biomedicale.univ-paris5.fr/aupossom).

Results and Conclusion:

Finally, we analyzed some pharmacokinetics and toxicological information
through the servers Aggregator Advisor (http://advisor.bkslab.org), Pred-hERG 4.0
(http://labmol.com.br/predherg) and pkCSM (http://biosig.unimelb.edu.au/pkcsm/prediction) which
we expect will be useful in in vitro preclinical trials.

Published: October 2018

To determine the molecular pathways of head and neck squamous cell carcinoma (HNSCC) tumorogenesis there are held a great amount of investigations. New therapeutic models for HNSCC are discussed considering genetic and biochemical specifications and taking in account significant scientific strategies. Dividing HNSCC into 2 large groups in accordance to human papilloma virus (HPV) association with different survival rates is a great achievement of the last decades in carcinogenesis researching and treatment of HNSCC. It is well known that chemical carcinogens are the main cause of HPV-negative tumors development. HPV-positive HNSCC is associated with E6 and E7 HPV proteins. The results of whole exome sequencing of HNSCC are of the great interest. Molecular expression profile of Rb-E2F/p53 were diff erent in HPV-positive and HPV-negative tumors. The phosphorylated pRb and p16 proteins analysis showed low pRb and high p16 levels in HPV-positive tumors in contrast to HPV-negative samples due to the HPV E7 ability to degrade Rb. P16 expression was higher in HPV-positive tumors, so it is immunohystochemical marker of HPV-positive status. The p53 expression pattern is determined also to identify its mechanism of degradation in HPV-positive tumors. Due to carcinogenic HPV ability by inactivation of cell cycle regulators р53 and pRb with the help of E6 and E7 oncoproteins, mutations of TP 53 shouldn’t play leading role in HPV-induced tomorogenity. Nevertheless, there are controversial data concerning HPV-positive tumors that part of them gain p53-mutations at the same time having integrated HPV-genome. The p53 expression in HPV-positive samples was the same as if in the absence of HPV.

Objective: to assess perspectives using biomarkers for early detection of developing acute kidney injury (AKI) among patients during partial nephrectomy under the warm ischemia of the kidney. Materials and methods: data of 100 patients was assessed with a localized renal cancer Т1N0М0 aged 56,5±8,7 years. All the patients underwent partial nephrectomy under warm ischemia of the kidney. The concentration of the following “early markers of AKI” was tested in blood of the patients using the ELISA technique and standard test-systems: cystatin С (BioVendor, Czech Republic), NGAL (BCMDiagnostics, USA), L-FABP (Hycult Biotechnology, Netherlands). The duration of warm ischemia was also fixed and the rate of diuresis was valued either. The test was carried out 24 hours prior to and 16 hours after the surgical interference. All the patients were diagnosed and classified by the presence or absence of AKI during the early postoperative period according to the generally accepted classification KDIGO. The obtained results were processed with the help of Microsoft Excel software, the statistical reliability of the results was defined on the basis of the use of Wilcoxon non-parametric test. Simultaneously the expert analysis of the clinical data and results of the laboratory research was carried out. Results: the method of the early diagnostics of AKI among patients who underwent partial nephrectomy under the warm ischemia of the kidney was developed. The method is based on the successive identification of the concentration of the early biochemical markers of AKI, the duration of warm ischemia and the rate of diuresis. Conclusions: the use of the developed method allows diagnosing the development of AKI among patients undergoing partial nephretomy under the warm ischemia already in 16 hours after the surgical interference (before the rise in the creatinine level).

Distinguishability times and asymmetry monotone-based quantum speed limits in the Bloch ball
Authors: Volkoff T.J. , Whaley K.B.
Published: October 2018

For both unitary and open qubit dynamics, we compare asymmetry monotone-based bounds on the minimal time required for an initial qubit state to evolve to a final qubit state from which it is probabilistically distinguishable with fixed minimal error probability (i.e., the minimal error distinguishability time). For the case of unitary dynamics generated by a time-independent Hamiltonian, we derive a necessary and sufficient condition on two asymmetry monotones that guarantees that an arbitrary state of a two-level quantum system or a separable state of N two-level quantum systems will unitarily evolve to another state from which it can be distinguished with a fixed minimal error probability δ∈[0,1/2]. This condition is used to order the set of qubit states based on their distinguishability time, and to derive an optimal release time for driven two-level systems such as those that occur, e.g., in the Landau-Zener problem. For the case of non-unitary dynamics, we compare three lower bounds to the distinguishability time, including a new type of lower bound which is formulated in terms of the asymmetry of the uniformly time-twirled initial system-plus-environment state with respect to the generator HSE of the Stinespring isometry corresponding to the dynamics, specifically, in terms of ‖[HSE,ρav(τ)]‖1, where ρav(τ):=1τ∫0τdte−iHSEtρ⊗|0⟩E⟨0|EeiHSEt.

Published: October 2018

Caravanserai refers to the accommodation for travelers to rest and enjoy the services provided there. Initially, it was known as ribat and khanqah. Its construction in Islamic civilisation is linked to tourism, which in turn generates the national economy. Besides that, its construction is made up of specific architecture. Thus, it is useful to promote the uniqueness of the country’s art, culture, and heritage as the main catalyst for the growth of the country’s tourism and cultural sector. The objective of this study was to examine the relationship between caravanserais in Islamic civilisation and the tourism industry, and how it can be used to promote art, cultural, and national heritage tourism in Malaysia. The study presented a qualitative research design using historical study and content analysis approach. The sampling of the study was done in two stages, namely article search based on the use of keywords such as caravanserai, Islamic tourism, art tourism, cultural tourism, and Islamic civilsation, and review of the reference list at the end of the articles that were referred to in the early stages. Meanwhile, data analysis was also conducted in stages, i.e., the analysis of the written content followed by the implied content. The research findings showed that caravanserai has a significant relationship with the tourism industry in Islamic civilisation based on three things. First, its position is on the Silk Road, which was a trade and tourism route at that time. Second, the caravanserai is a tourist attraction because it has historical places and functions as a commercial center. Third, the caravanserai contributes to the economic growth of the country as it successfully attracts many tourists to visit the place. The research findings also indicated that the caravanserai can be used to promote art, cultural, and national heritage tourism in Malaysia based on its construction as a historical monument that displays certain arts and becomes a tourist destination for local history and cultural exploration. This finding is also supported by previous studies which agreed that culture and art can be used to promote tourism. Thus, the concept of caravanserai construction in Islamic civilistion can be utilised towards promoting the tourism industry in Malaysia in line with the National Tourism Policy (NTP) 2030, which, among other things, focuses on the keystones to improve the experience and satisfaction of tourists.
Stagnation generation: Evaluating the impact of higher education expansion on social mobility from the perspective of Taiwan
Authors: Lin Yen-Ling
Published: October 2018

Social class stagnation is a current topic of concern. The stagnation of generational mobility could result in society losing its ability to enhance individuals? social status. This study explored higher education expansion as a possible cause of class stagnation by adopting the Human Development Index as a comprehensive indicator of individual social status, and determined dynamic mobility by observing the case of Taiwan, where higher education was expanded in 1994. Pseudo-panel data were obtained from the Family Income and Expenditure Survey. Our results indicate that rapid higher education expansion has a negative impact on social mobility for the generation who enters the labor market after the expansion starting point.
Transcription Factor 7-Like 2 (TCF7L2) Gene Polymorphism and Progression From Single to Multiple Autoantibody Positivity in Individuals at Risk for Type 1 Diabetes
Authors: Redondo Maria J. , Steck Andrea K. , Sosenko Jay , Anderson Mark , Antinozzi Peter , Michels Aaron , Wentworth John M. , Atkinson Mark A. , Pugliese Alberto , Geyer Susan ,   the Type 1 Diabetes TrialNet Study Group
Published: October 2018

OBJECTIVE

The type 2 diabetes–associated alleles at the TCF7L2 locus mark a type 1 diabetes phenotype characterized by single islet autoantibody positivity as well as lower glucose and higher C-peptide measures. Here, we studied whether the TCF7L2 locus influences progression of islet autoimmunity, from single to multiple (≥2) autoantibody positivity, in relatives of patients with type 1 diabetes.

RESEARCH DESIGN AND METHODS

We evaluated 244 participants in the Type 1 Diabetes TrialNet Pathway to Prevention study with confirmed single autoantibody positivity at screening and Immunochip single nucleotide polymorphism data (47.5% male; median age 12.8 years, range 1.2–45.9; 90.2% white). We analyzed risk allele frequency at TCF7L2 rs4506565 (in linkage disequilibrium with rs7903146). Altogether, 62.6% participants carried ≥1 risk allele. Univariate and multivariable Cox proportional hazards models and Kaplan-Meier statistical methods were used.

RESULTS

During follow-up (median 5.2 years, range 0.2–12.6), 62% of the single autoantibody–positive participants developed multiple autoantibody positivity. In the overall cohort, the TCF7L2 locus did not significantly predict progression to multiple autoantibody positivity. However, among single GAD65 autoantibody–positive participants (n = 158), those who carried ≥1 risk allele had a lower rate of progression to multiple autoantibody positivity (hazard ratio [HR] 0.65, P = 0.033) than those who did not, after adjustment for HLA risk haplotypes and age. Among subjects who were either IA-2 or insulin autoantibody positive only, carrying ≥1 TCF7L2 risk allele was not a significant factor overall, but in overweight or obese participants, it increased the risk of progression to multiple autoantibody positivity (HR 3.02, P = 0.016) even with adjustment for age.

CONCLUSIONS

The type 2 diabetes–associated TCF7L2 locus influences progression of islet autoimmunity, with differential effects by autoantibody specificity and interaction by obesity/overweight.
Use of a Metabolic Syndrome Severity Z Score to Track Risk During Treatment of Prediabetes: An Analysis of the Diabetes Prevention Program
Authors: DeBoer Mark D. , Filipp Stephanie L. , Gurka Matthew J.
Published: October 2018

OBJECTIVE

We assessed whether changes in metabolic syndrome (MetS) severity during the treatment of prediabetes are associated with reduced risk of type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD).

RESEARCH DESIGN AND METHODS

We analyzed data from the Diabetes Prevention Program (DPP) for 2,476 adults in 1996–1999 with prediabetes randomized to receive treatment with lifestyle modification, metformin, or placebo for 2–3 years and followed through 2014 for T2DM and CVD outcomes. We calculated effect sizes from baseline in a MetS severity z score (MetS-Z) and the individual MetS components, and assessed relationships between 1-year effect size and incident T2DM and CVD using hazard ratios (HRs) and mediation analysis.

RESULTS

Baseline MetS-Z and its components were associated with risk of incident T2DM and CVD. During year 1 of intervention, MetS-Z and its components decreased most with lifestyle modification, followed by treatment with metformin and placebo. Risk of T2DM within 1–5 years was most strongly associated with 1-year changes in MetS-Z and waist circumference (both HRs for a 1 SD increase = 1.80), whereas the risk of CVD was associated with a 1-year change in MetS-Z, glucose, and systolic blood pressure. In mediation analyses, the effect of lifestyle modification on T2DM risk was mediated by 1-year changes in MetS-Z, waist circumference, glucose, and triglycerides, whereas the effect of metformin was mediated by MetS-Z and glucose.

CONCLUSIONS

Changes in these risk indicators of MetS severity during intervention in the DPP reflect altered disease risk and may help in tracking earlier responses to treatment and in motivating patients.

Impact of the electron-phonon coupling factor and electron heat capacity on the thermal response of targets irradiated by femtosecond laser
Authors: Al-Malkawi G. H. , Hassanein A.
Published: October 2018

This work investigates the impact of the electron temperature-dependent electron-phonon coupling factor and the electron heat capacity on the thermal evolution of a copper target irradiated by femtosecond laser pulses. These effects were studied using their recently developed two-dimensional two-temperature model. Two models were implemented to account for the electron-phonon coupling calculation. The first were the calculations of the electronic structure of the density of state have been done at high electron temperature. The excitation of the d-band electrons and their contribution to the coupling of the heat between electrons and phonons were considered. The second were the electron-electron collisions and electron-lattice collision rates calculations were performed. The effect of fluence on the thermalization time and on the ablated depth of the copper irradiated by femtosecond laser pulses was studied using these two models and compared with the results assuming constant value for the electron-phonon coupling factor. A comparison between the model of the electron heat capacity based on the density of state calculation and the well-known linear relationship between the electron heat capacity and the electron temperature was also studied.

Published: October 2018

Introduction.  Power  parameters  of  the  “rolling  −  equalchannel angular pressing” (ECA) combined process are studied. The work objective is to determine forces of rolling and pressing in the deformation by the combined method.

Materials and Methods. The die strength calculation and the experiment on deformation of AISI 6063 aluminum samples were carried out. During the experiment, the force values were recorded using a strain-gauge station.

Research Results. The strength analysis results show that this die design is suitable for creating an experimental stand of the “rolling − ECA-pressing” combined process, since the calculated  safety  margin  is  sufficient  to  implement  the  pressing under extreme conditions. The rolling forces at all stages of the  deformation  exceed  the  corresponding  pressing  forces, which is a necessary condition for the combined process. Discussion and Conclusions. The obtained results can be used in the design of experimental stands that implement the investigated combined  process. Herewith, the given  strain-gauge method for studying strength characteristics is suitable for the case of calibrated rolls.

Authors: Al Muslamiya Sheikha Salim , Osman Abdel Rahman Sofy
Published: October 2018

In recent years, the family in the Arab and Gulf countries has experienced many structural changes because of various transformations that have contributed to changing some of its functions. The modern Omani family has witnessed some radical changes in its structure consistent with the recent developments in the Sultanate. These changes occurred in various economic, social, political and cultural fields, which led to the spread of some modern phenomena, including the phenomenon of travelling abroad. According to the latest statistics issued by the National Center for Statistics and Information in the Sultanate of Oman, there is an increase in the number of Omanis departing from the Sultanate, which accounted for 77.7% of the total departures from the Sultanate during August 2017. There are many social, economic, cultural, health, and other factors that drive families to travel abroad. While imitation and simulation of relatives or peers are behind travelling abroad, others see it as means to gain a high social status or as an opportunity to strengthen social relations between family members. Of course, for many others the main driving factor is seeking medical checkup and treatment. Thus, the research problem focuses on identifying the factors that drive the Omani family to travel outside the Sultanate. The researchers relied on the analytical descriptive method using a comprehensive social survey. The research instrument was administered among parents (fathers or mothers) of third year students majoring in sociology or social work, as well as students registered in the college required philosophy course for the fall semester of 2017.The study found that there are many social, economic, cultural and health factors that drive Omani families to travel abroad. It also provided suggestions, along with some mechanisms that are useful in rationalizing the travel of Omani families abroad.
The Umayyads’ Intermarriages: Its Political and Administrative Impacts on the Umayyad State (41-132 H / 661-749 AD)
Authors: Alzowy Huda Fahad
Published: October 2018

Intermarriages represent a form of social connections that occur for common reasons. However, they may also occur for special reasons such as strengthening the relationship of certain families, achieving a tribal alliance, raising the social status of a family, or gaining economic benefits.This study addresses the theme of Umayyad intermarriages and tries to figure out its general nature and whether it had clear political or administrative impacts and how the sources were interested in clarifying these impacts. This research is divided into two sections: the first focused on Umayyad men and women intermarriage, both Sufiani and Marwani. This study adopted two sources of pedigree books: Zubairi (d. 236 AH) Quraish Pedigree and Al-Baladhuri (d. 279 AH) Ashraf pedigree which aim to identify the general nature of Umayyad family intermarriages and the extent of social openness to other Quraish families in particular and Arab tribes in general. The researcher used the statistical method.The second section focused on searching the impacts of intermarriage on the political and administrative conditions in the Umayyad dynasty by relying on historical sources and identifying the extent to which those sources were interested in linking those situations to intermarriage.

Algerian press and document the views of the Algerian and Omani on topical issues. Among the findings of the research is the extrapolation of the huge amount of Algerian press material covered by the period of study. That the reasons of Omani-Algerian relationship extend in the depths of history, back to the second century AH, and she has stimulated the efforts of the press pioneers in Algeria and Zanzibar this relation and contributed to its consolidation in this modern age. The study also concluded that the image of the Sultanate of Oman in this press embodies a mosaic of high cultural characteristics. The first is: Oman's adherence to its religious and Arab identity. The second is: his struggle for his freedom and his struggle against colonialism throughout history. The third is: the wrapping of the Omani people around their political leadership and their pride in their scientists. The fourth: the sense of citizenship and co-existence and the entrenchment of the right to difference. The fifth: focus in the renaissance on the humans before the structures, and finally, the image of the Sultanate of Oman in short is: "Is the originality of history, the renaissance of the future, and a worthy example to study and follow-up".

Published: October 2018

This study is concerned with benchmarking the hotel industry in the Sultanate of Oman besides identifying the environmental factors that influence the operational efficiency of hotels. The benchmarking analysis is carried out through data envelopment analysis (DEA), used essentially to evaluate the efficiency ratios of a selected sample of 58 hotels. Although less than 23% of the hotels are found efficient, the average efficiency score of 83% indicates a reasonable efficiency in resource management for most of the hotels. Regarding the contextual effects, hotel Size, Star rating and cultural attractions are found to have the most significant effect on hotel efficiency in Oman. The positive effect of cultural attractions can inform policy makers on the necessity to preserve and promote cultural heritage as an important key factor of attraction.

Samples of pristine poly vinyl chloride (PVC) and other samples of the same matrix containing a variable amount of inorganic sodium salt (sodium chloride NaCl) were prepared via simple casting route in a dimethyl sulfoxide (DMSO) solvent were prepared. Prepared samples were characterized via x-ray diffraction (XRD) measurements and Fourier transform infrared spectrophotometric measurements (FTIR) in combination with computational density functional theory approaches (DFT) into account for a detailed picture of the possible reaction mechanisms within the polymeric matrices. All measurements were performed on the possible basis set. Local density approximate (LDA) and generalized Goertzel algorithm (GGA) was also tested. A compatibility between computed and experimental results suggested that physical interaction was preferred in such matrix and nominate use of this new material to be used in the medical field as a result of dioxin illumination.
Oğlaklarda Organik Bakır ve Çinko İz Minerallerinin Canlı Ağırlık ile Bu Minerallerin Birikim ve Atılma Düzeyleri Üzerine Etkisi

Bu çalışma, oğlakların rasyonuna eklenen inorganik bakır ve çinko ile inorganik formlarına göre %50 oranında daha düşük düzeylerde eklenen organik bakır (Cu) ve çinko (Zn) minerallerinin canlı ağırlık artışı, serum ve kıl ortalama değerleri ile dışkıda atılan miktar üzerine etkisini değerlendirmek için gerçekleştirilmiştir. Oğlaklara verilen rasyonun içerdiği bakır ve çinko minerallerine göre organik (deneme, n=12) ve inorganik (kontrol, n=12) olarak iki gruba ayrılmıştır. Kontrol grubuna bakır-sülfat 7 mg/kg KM, çinko-sülfat 20 mg/kg KM, deneme grubuna ise bakır-şelat (2-hydroxy–4-methylthiobutyrate) 3,5 mg/kg KM ve çinko-şelat (2-hydroxy–4-methylthiobutyrate) 10 mg/kg KM verilmiştir. Çalışma sonunda her iki grubun serum bakır ve çinko ile kıl bakır ve çinko ortalama değerlerinin deneme başına göre daha yüksek düzeyde olduğu saptanmıştır. İki gruba ait canlı ağırlık, serum bakır ve çinko ile kıl bakır ve çinko ortalama değerleri arasındaki farkın istatistiksel açıdan önemli olmadığı belirlenmiştir. Serum bakır ve çinko ile kıl bakır ortalama değerlerinin organik grubunda, kıl çinko ortalama değerinin ise inorganik grubunda rakamsal olarak daha yüksek düzeyde olduğu belirlenmiştir. Araştırmada dışkı çinko ve bakır ortalama değerlerinin organik grubunda inorganik gruba göre önemli oranda daha düşük olduğu görülmüştür. Sonuç olarak oğlakların rasyonuna organik bakır ve çinko inorganik formlarına göre %50 oranında daha düşük düzeylerde eklenmesine rağmen canlı ağırlık artışı, serum ve kıl ortalama değerleri bakımından inorganik bakır ve çinko ile benzer değerler elde edilmiştir. Bu değerler organik minerallerin daha iyi emildiklerini göstermektedir. Ayrıca organik mineral grubunda dışkı bakır ile dışkı çinko ortalama değerlerinin daha düşük düzeyde belirlenmesi, çevreye daha az miktarda saçıldıkları ve dolayısıyla çevreyi daha az kirlettikleri kanaati oluşturmuştur.
Determination and Assessments the Yield Gap Between the Wheat Yield and Potential Yield in Turkey
Authors: Atar Bekir
Published: October 2018

Knowing the current and the potential production amount of wheat is essential to meet the growing needs. Yield is determined by many factors. The main factors that limit the potential yield are genetic characteristics, and climatic factors such as rainfall and radiation, and management. Wheat is mostly grown in non-irrigated areas in Turkey. The most significant factors that limit dry agriculture wheat production yield in the Mediterranean climatic type are rainfall and its distribution in the growing season. A steady increase in yield is observed in Turkey in recent years. Average annual wheat production is 20.6 million tons. The potential production in this work is determined as 54 million tons. The gap is about 33 million ton. The actual production is 39% of the potential production. The average yield of the Growing Season Rainfall (GSRF) 500 mm areas is 2.2 t ha-1, and the potential yield is 8.8 t ha-1. The gap between the actual yield and potential yield is quite large. The current yield between the areas (GSRF 500 mm) is very small. So it is difficult to explain the gap just because of the rainfall.

Published: October 2018

The study investigated the effects of oregano- or red pepper-essential oil at delayed feeding (0, 24 and 48 h post-hatching) on performance and morphological development of small intestine segments. Female broilers were fed one of 3 rations including a control ration with no essential oil (CONT), the rations added with either oregano essential oil (OEO) or red pepper essential oil (RPEO) at 250 mg/kg to CONT. A total of 18 chicks from each treatment were used to measure the morphological parameters of the small intestine segments on the 14th day. Prolongation of accessing time to ration significantly decreased the body weights of broilers at 3rd, 7th and 14th d, feed intake (FI) from 4 to 7 d and improved feed conversion ratio (FCR) of broilers at the period of 4-7 d. Access to ration for 48 h post-hatching significantly decreased the body weight gains at the period of 4-7 and 7-14 d, FI from 7 to 14 d and improved FCR of broilers at the period of 7-14 d. OEO250 ration significantly increased villus height (VH) and villus surface area (VSA) of jejunum (J) and ileum (I) of broilers fed immediately and the IVH and IVSA of broiler accessed to ration for 48 h post-hatching. VH of duodenum (D), IVH and IVSA of broilers fed for 24 h post-hatching were significantly increased by RPEO250 ration. OEO250 and RPEO250 rations significantly reduced crypt depth (CD) of D and J of broiler accessed to ration for immediate and DCD of broiler fed for 24 h post-hatching. OEO250 and RPEO250 rations significantly increased IVH and IVSA and reduced DCD, JCD and ICD of broilers. In conclusion, OEO250 and RPEO250 rations affected positively VH and VSA of I and reduced CDs of small intestine segments of broilers accessed to ration at different times.
Regression Analysis for the Factor Affecting on Farm Land/Urban Land Value in Urban Sprawl
Authors: Karakayacı Zuhal
Published: October 2018

In this study, the factors affecting on land value in urban sprawl were analysed via regression analysis. In the analyse, the nominal value of land was taken to be dependent variable while factors affecting the value of the land in urban sprawl were considered to be independent variables. 9 factors that were thought to affect the value of the land were handled. In this study, 3 separate models were analyzed, and all models provided statistically significant results. The basic reason for applying three separate models is to be witness the effects by including the variables in different categories (environmental, social amenity and economical factors) separately to the model. As a result of these analyses, all of environmental, amenity and economic factors should be considered for valuation of urban sprawl.

Purpose: To determine the positive predictive values (PPV) of Ontario administrative data codes for the identification of open (OSR) and endovascular (EVAR) repairs of elective (eAAA) and ruptured (rAAA) abdominal aortic aneurysms.

Methods: We randomly identified 319 eAAA and rAAA repairs at two Toronto hospitals between April 2003 and March 2015, using administrative health data in Ontario, Canada. International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10) codes I71.3 and I71.4, were used to identify rAAA and eAAA patients, respectively. A blinded retrospective chart review was conducted and served as the gold standard comparator. Re-abstracted records were compared to Canadian Classification of Health Interventions (CCI) and Ontario Health Insurance Plan (OHIP) codes in the Canadian Institute for Health Information Discharge Abstract Database (CIHI-DAD) and OHIP databases. We calculated the PPV and 95% confidence intervals (95% CI) of individual and combined procedure and billing codes for elective and ruptured OSR and EVAR (eOSR, eEVAR, rOSR, and rEVAR).

Results: Permutation of codes allowed identification of eOSR with 95% PPV (95% CI 88, 98), eEVAR with 96% PPV (95% CI 90, 99), rOSR with 87% PPV (95% CI 79, 93) and rEVAR with 91% PPV (95% CI 59, 100).

Conclusions: Diagnostic, procedure and billing code combinations allow identification of eOSR, eEVAR, rOSR and rEVAR patients in Ontario administrative data with a high degree of certainty.

Published: October 2018

Recovery service failures can affect a greater failure if not handled properly. The purpose of this study was to examine the effect of pre-recovery emotions and post-recovery in services. Data were collected using a questionnaire distributed to 216 respondents who have used the services retail market and then experienced a service failure followed by a recovery service. In this study, positive and negative emotions post-recovery are the dependent variables, while the severity of service failure, the pre-recovery emotions and perceived fairness other variables major variable. In line with this goal, eight hypotheses were tested using structural equation modeling analysis with the aim to clarify the relationships between variables. The results show that the post-recovery of positive or negative emotions are influenced by the severity of the failure of the service, but the effect is mediated by the second pre-recovery emotions. Meanwhile, there is no mediating effect of perceived justice on the emotions of pre-recovery and post-recovery. This study implies that, during recovery services, service providers must simultaneously consider the positive and negative emotions. In addition, managers should also consider the depth of the severity of service failure to determine the pre-recovery emotions. Selection of the type of recovery will have an impact on the perceived fairness, so that providers have to respond better to emotional recovery.
