Various Size-sorting Processes for Millimeter-sized Particles in the Sun’s Protoplanetary Disk? Evidence from Chondrules in Ordinary Chondrites

Chondrules are approximately millimeter-sized beads of crystallized silicate melt. They formed mainly in the first ∼3 Ma of the Sun’s protoplanetary disk and are the main constituents of chondritic asteroids. Here we report on the size–frequency distributions (2D and 3D) of chondrules in the brecciated ordinary chondrite (OC) Northwest Africa (NWA) 5205. We investigated three large (centimeter- to decimeter-sized) chondritic lithic clasts of a particular textural type (“cluster chondrite”) with eye-catching different chondrule sizes. One clast shows the largest mean chondrule size (∼1.5 mm) ever measured in a chondrite. As in the other OCs, we find a positive correlation between the minimum and mean chondrule size, which we consider as an argument for chondrule size sorting. Chondrule size–frequency distributions in the clasts are distinctly more symmetric than the about log-normal distributions in other OCs. Furthermore, we find a co-enrichment of chondrule types with a priori small mean sizes (type I, porphyritic) in clasts with overall small mean chondrule sizes. We consider this as the fingerprint of an additional/second size-sorting process, which acted later on these chondrule populations. This process possibly subdivided a typical LL-type chondrule population into several subpopulations with different mean chondrule sizes. We speculate that this second sorting occurred in a unidirectional gas stream or headwind, e.g., by settling of chondrules through an asteroidal atmosphere or interaction with an expanding impact plume. Possibly, fine-grained matrix was almost completely removed by this, and the size-sorted chondrule subpopulations accreted in a hot state separately in different regions of the asteroid.
Long‐term follow‐up of Langerhans cell histiocytosis: 39 years’ experience at a single centre

Aim: To evaluate the long‐term outcome of Langerhans cell histiocytosis (LCH) in children. Methods: We re‐evaluated all children (<15 y old at diagnosis) treated at our unit in 1962–1989. Histopathology specimens were reviewed and verified for 49 patients. Forty patients underwent physical examination and laboratory tests, and 38 were subjected to imaging, at a median time of 16 y (range 5.5–33.5) after diagnosis. Results: Altogether, 5/49 (10%) children died, all with multi‐system disease and age <2 y at diagnosis. Age at diagnosis (p=0.001) and survival (p=0.014) for the 22 children with multi‐system disease was significantly lower compared with the 27 children with single‐system disease. The term “maximal extent of disease” was introduced since reactivation of LCH often tends to involve additional organs not previously affected by the disease. At follow‐up, late sequelae had developed in 17/40 (42%) patients, including diabetes insipidus in 6/40 (15%), CNS complications in at least 4/40 (10%) (3/16, 19%, of multi‐system patients) and late‐stage pulmonary disease in 4/38 (11%). Seven out of 21 (33%) of the patients with multi‐system disease were alive and healthy without sequelae at follow‐up, as compared to 16/24 (67%) of those with single‐system disease (p=0.026). Of 14 individuals 25 y at follow‐up, senior high school had been completed in 7/9 (78%) with single‐system and 1/5 (20%) with multi‐system disease (at maximal disease extent) (p=0.091).
Chikungunya Fever in Clinically Diagnosed Patients: A Brief Report of Comparison Between Laboratory Confirmed and Discarded Cases

Objectives: In 2015, a total of 1607 chikungunya cases were conﬁrmed in Yucatan, Mexico, where they all took place in the second half of the year, meaning a simultaneous occurrence of both chikungunya and dengue outbreaks. This coexistence of both out-breaksposedachallengetodiﬀerentiateclinicaldiagnosis. Thecurrentstudyaimedatidentifyingsignsandsymptomstoclinically discriminate chikungunya from dengue fever in ambulatory cases. Methods: The results of a case series observational, descriptive, retrospective study of suspected ambulatory patients whose samples were referred to the laboratory for polymerase chain reaction (PCR)/serum analysis from August to December 2015 were pro-vided. Results: The study included 181 cases of which 152 were positive, ﬁnding that pruritus was a suggestive symptom of an acute infection caused by chikungunya virus (CHIKV). Polyarthralgia and pruritus were signiﬁcantly associated with chikungunya conﬁrmed cases, compared with discarded cases. Conclusions: Polyarthralgia and pruritus are suggestive symptoms of an acute infection caused by CHIKV.
THE IMPACT OF BOARD INDEPENDENCE, WOMEN ON BOARD AND AUDITOR INDEPENDENCE ON THE FRAUD: EVIDENCE FROM JORDANIAN FIRMS

In developing economies, fraud is an important subject due to the impact on the financial reporting quality. This study discovers the impact of board independence, women on board and auditor independence on the fraud in financial reporting for a sample covers of 86 year observations of industrial firms listed in Amman Stock Exchange from 2015 to 2016. In this study, income smoothing was a proxy for fraud in financial reporting. Using the multiple regression analysis, the results revealed that board independence and auditor independence plays the key role in prevention the fraud in financial reporting. This study concluded that more independent directors would make lower fraud in financial report. This study provides evidence that the provision of NAS by an external auditor positively contributes to fraud in financial reporting. Nevertheless, the outcomes show that the women on board do not have any effect on the fraud in the financial reporting among industrial Jordanian firms. The current study contributes to the existing literature of fraud and stimulates future research about the factors determinants of the fraud in financial reporting in other developing countries.
Inhibitory control, brain function and exercise in special populations

Inhibitory control is an executive function based on the prefrontal cortex (PFC) and is suggested to play a key role in healthy behaviors. Impairment of this cognitive function has been described in individuals with substance use disorder (SUD) and obesity. On the other hand, aerobic exercise and cardiorespiratory fitness has been shown to improve inhibitory control suggesting its potential role in preventing and treating impulsivity and unhealthy behaviors. Here we present four studies that investigated the interaction between inhibitory control, brain function, and exercise in individuals with substance use disorder and children with different body composition. In the first study, we review the chronic effects of aerobic exercise in individuals with SUD and propose a psychobiological model of exercise for future clinical trials in this population. On the second study, we showed the acute effects of aerobic exercise on inhibitory control and PFC oxygenation in individuals with SUD. On the third study, we showed how fat mass in children was associated with poorer foodspecific inhibitory control, independent of the cardiorespiratory fitness. And, in the fourth study, using an MRI scanner, we have identified the neural correlates associated with the food-specific inhibitory control in children. Together, our studies showed the potential benefits of keeping healthy behaviors, such as aerobic exercising and decreased levels of fat mass, on inhibitory control and brain function in special populations.
COMMUNITY PHARMACISTS’ ATTITUDES TOWARD COLLABORATION WITH PHYSICIANS

Objective: Healthcare providers play a key role in reducing medication errors and improving patient care, especially for those who suffer with chronic diseases. This study aims to assess pharmacist attitudes toward collaborative practice in northeastern Iran. Methods: A face-to-face survey was offered to a sample of 124 pharmacists in Mashhad, Iran, and some other cities of the Razavi Khorasan province. This survey assessed the following elements of community pharmacists’ collaborative behavior: “interactional determinants,” “environmental determinants,” and “pharmacist determinants. ” Results were analyzed to determine how pharmacists’ attitudes and other variables would influence their collaborative behavior. Results: The survey response rate was 100%. Principal component analysis revealed that the attitudes towards collaboration instrument for pharmacists (ATCI-P) in our sample consisted of two factors: interactional determinants and pharmacist determinants, both with high internal consistency (Cronbach’s alpha = 0.83). The lowest and the highest scores in the interactional determinants domain were 19 and 35, respectively. The higher attitudes toward collaboration were obtained in the capital city, Mashhad, rather than in towns (P-value = 0.006). Multiple linear regression analysis of the complete model was significant (R = 0.36, P-value = 0.005). The age and city/community size were also found to be significant predictors of collaboration behavior (B = 0.300, p = 0.002 and B = 0.259, p = 0.004, respectively). Conclusion: The community pharmacists in Razavi Khorasan, Iran, have a profound attitude toward collaboration with physicians, and their collaborative behavior is influenced by the age and community size.
Vein Patterning by Tissue-Specific Auxin Transport

Unlike in animals, in plants vein patterning does not rely on direct cell-cell interaction and cell migration; instead, it depends on the transport of the plant signal auxin, which in turn depends on the activity of the PIN-FORMED1 (PIN1) auxin transporter. The current hypotheses of vein patterning by auxin transport propose that in the epidermis of the developing leaf PIN1-mediated auxin transport converges to peaks of auxin level. From those convergence points of epidermal PIN1 polarity, auxin would be transported in the inner tissues where it would give rise to major veins. Here we tested predictions of this hypothesis and found them unsupported: epidermal PIN1 expression is neither required nor sufficient for auxin-transport-dependent vein patterning, whereas inner-tissue PIN1 expression turns out to be both required and sufficient for auxin-transport-dependent vein patterning. Our results refute all vein patterning hypotheses based on auxin transport from the epidermis and suggest alternatives for future tests.
Confirmatory Factor Analysis of Absorptive Capacity and Competitiveness of Small and Medium-Sized Enterprise of Thailand’s Gems and Jewelry Industry

The objective of this research was to synthesize and analyze the confirmatory factors of absorptive capacity and competitiveness of small and medium-sized enterprises (SMEs) of Thailand's gems and jewelry industry according to the hypothesis model and empirical data. The sample of this research was 270 SME executives or entrepreneurs. Multi-Stage-Sampling was used to select the sample. Data were analyzed with Confirmatory Factor Analysis. The results of this study indicated that 1) there were 10 causal factors of absorptive capacity in three aspects, were ordered based on highest to lowest factor loading as follows: environmental turbulence, external source, and social integration mechanism. The factor loading values of three factors were 0.65, 0.54 and 0.43, respectively. The model was consistent with empirical data. 2) There were 8 causal factors of competitiveness in three aspects, were ordered based on highest to lowest factor loading as follows: potential capacity, realize capacity, and competitiveness. The factor loading values of three factors were 0.86, 0.71, and 0.40, respectively. The model was consistent with empirical data (X2 - test = 16.20, df = 13, p-value = 0.24, CFI = 1.00, GFI = 0.99, AGFI = 0.96, RMSEA = 0.030, SRMR = 0.021) Which is a model that is suitable for use in the context of SME’s that use primary technology in Thailand.

The Therapeutic vs. Constructive Approach to the Transformative Character of Collective Intentionality. The Interpersonal Level of Explanation

In their article, Andrea Kern and Henrike Moll (2017) argue in support of a certain vision of shared/collective intentionality and its role in understanding our cognitive capacities. This vision is based on two aspects: a negative one, i.e. a theoretical diagnosis of the contemporary debate on shared/collective intentionality, and a positive one, referring to the proposals for shared/collective intentionality. As regards the negative aspect, the main thesis concerns the arbitrary assumptions underlying the whole debate on shared/collective intentionality. According to Kern and Moll (2017), this assumption prevents us from capturing the transformative character of shared/collective intentionality and therefore the uniqueness of the human being. This paper is not so much a detailed criticism or discussion of said article, as rather an opportunity to formulate my own position in the colloquy with Kern and Mole’s position. This approach states that understanding the transformative character of SI/CI requires taking into account a broader approach to the constitution of the mind, in which, apart from the personal and the sub-personal level of explanation, there is also a third level of explanation  the interpersonal level of explanation.

ADOPTION OF SOFTWARE AS A SERVICE (SAAS) IN SMALL AND MEDIUM-SIZED HOTELS IN TIRANA

Technology moves with a rapid pace and it has touched every aspect of the hospitality industry. Nowadays, this huge industry is facing significant technological changes especially in the hotel sector. With the continuing growth of modern technologies in hotel management (e.g. SaaS, PMS, CRM, smart devices, Internet of things), and other aspects of industry 4.0, readiness of sector representatives to adopt such new technological advancements appears as a worthy research topic. This research aimed to identify the adoption of SaaS (Software as a Service) technology in small and medium-sized hotels in Tirana, Albania and measure hotel owners/managers’ willingness to implement this technology in their properties. As part of the data collection process, a structured interview was conducted with 75 hotel owners and managers. Results show that SaaS technology implementation is very limited in the sampled hotels. Majority of the sampled hotels extensively rely on traditional property management systems. Nevertheless, other findings of the study show that hotel managements demonstrate high willingness to implement SaaS system in their hotel management. This willingness was found to be more prevalent among newly hired, more educated, younger managers as compared to older age hotel owners. A number of implications are discussed for local authorities, SaaS marketers and hotel managements to implement SaaS system in small and medium-sized hotels in Tirana.
Prognostic Factors for Non-small Cell Lung Cancer Treated with Carboplatin, Paclitaxel, and Bevacizumab

Background and objective: Carboplatin, paclitaxel, and bevacizumab (CPB) therapy is a treatment option for non-small cell lung cancer. Factors predicting the survival of patients receiving this therapy were investigated. Methods: From 2011 to 2016, 41 patients (excluding those positive for EGFR mutation or ALK fusion gene) received first-line CPB therapy. Prognostic factors for progression-free survival (PFS) and overall survival (OS) were investigated by the Cox proportional hazards model. Results: The median age was 70 years, 38 patients had adenocarcinoma, and 30 patients were men. Eastern Cooperative Oncology Group performance status (PS) was 0 /1 /2 in 10/ 29/2 patients. Overall PFS and OS were 6.4 and 10.9 months, respectively. According to univariate analysis, a neutrophil/lymphocyte ratio (NLR)>3.0 and hypoalbuminemia (serum albumin 3.0 vs. not: 6.3 vs. 11.2 months, p=0.00307, and 9.5 months vs. not achieved, p=0.0214; hypoalbuminemia vs. not: 5.5 vs. 9.7 months, p=0.0039, and 6.4 vs. 33.2 months, p= 0.000164). Conversely, a good PS was associated with significantly longer median PFS and OS (PS=0 vs. not: 11.1 vs. 6.1 months, p= 0.00537, and not achieved vs. 9.5 months, p=0.0343). Cox proportional analysis confirmed NLR>3.0 and hypoalbuminemia as poor prognostic factors (NLR>3.0 for PFS: hazard ratio (HR) 2.84, p=0.037; hypoalbuminemia for OS: HR 6.54, p=0.008432). However, good PS was not significant. Conclusion: In lung cancer patients receiving CPB therapy, the prognosis might be predicted by NLR, hypoalbuminemia, and PS.
FRAMING THE KILLING OF BIN LADEN IN NATIONAL PRESS: IMPLICATIONS FOR US PUBLIC DIPLOMACY

The killing of Bin Laden was arguably a watershed moment in the US led global war on terror. A considerable scholarship has been conferred about the media framing and US counterterrorism, intriguingly hitherto no academic study is available how the incident was framed in the national media milieu. This study makes a modest attempt to fill this academic lacuna by exploring how the national press of Pakistan framed the killing of Bin Laden in their editorial discourses and what could be its possible implications for the US public diplomacy. Drawing on the framing tradition as framework and qualitative analysis as methodology, the study findings reveal three dominant discursive frames the press employed to construct the narratives about the killing of Osama Bin Laden and the events ensued namely: Ambivalence/ US-staged drama, Sovereignty violation, and Pakistan under US threat to overarching anti-American frame. The discussions elaborate the contribution of the study and the implications for the US public diplomacy toward Pakistan
Stressors at the work-family interface and satisfaction with the quality of the couple relationship: a comparative analysis of men and women

ABSTRACT This study examined the contribution of stressors deriving from the work-family interface to explaining two aspects of the quality of the couple relationship among men versus women: satisfaction with sexual life and satisfaction with couplehood. The sample comprised 276 heterosexual Israeli participants (136 men, 140 women). The examined stressors included objective overload at home and at work (assessed by the number of hours devoted daily to each domain), subjective overload, and the experience of role conflict (family interferes with work [FIW], and work interferes with family [WIF]). The data were analyzed using structural equation modelling. For both genders, satisfaction with the daily amount of time that the partner devotes to the home and family domains explained satisfaction with sexual life and satisfaction with couplehood. Among women, satisfaction with sexual life was explained by the experience of WIF conflict, whereas satisfaction with couplehood was explained by the experience of FIW conflict. Furthermore, egalitarian gender-role attitudes correlated positively with men’s sexual satisfaction and negatively with the intensity of FIW conflict. We concluded that for women, work-family stressors affected the quality of the couple relationship, whereas the impact of egalitarian gender-role attitudes on the quality of the couple relationship was greater for men.
Inclusive Instruction for Students Receiving Special Education Services for Emotional Disturbance: A Survey Development Study

Although the majority of students receiving special education services for emotional disturbance (ED) receive a significant amount of instruction in general education classrooms, evidence-based practices for educating students with ED in these settings have yet to be identified. As a result, school-based practitioners must primarily rely on professional recommendations and values when planning and delivering inclusive instruction for this student population. This study investigated the internal consistency and factor structure of a survey measure designed to obtain information on practitioner knowledge, use, and perceived effectiveness of recommended classroom-based practices for the inclusive instruction of students with ED. Results indicate adequate internal consistency. An exploratory factor analysis (EFA) revealed a four-factor structure: Behavior Support, Classroom Management, Differentiation, and Instructional Practices. Study limitations include a low response rate for the electronic survey and reliance on responses from practitioners from one geographic area. Future investigations are necessary to refine the survey instrument and to obtain data from teachers from other geographic areas.
[RETRACTED: Concurrent Programming 2019: COURSE PROJECT 6]

This paper is presenting a lock-free cuckoo hashing algorithm. [1] The algorithm allows modifying operations to operate as one with search ones and requires only single word compare-and-swap primitives. Searching of items can operate concurrently with others mutating operations, thanks to this two-round query protocol that has been enhanced with a logical clock technique. When an insertion triggers a sequence of key displacements, rather than locking the path, the algorithm will break down the relocation sequence into single relocations which can be executed independently and concurrently with other operations. A finely tuned synchronization and a helping mechanism for relocation are designed. The mechanisms will allow high concurrency and provide progress guarantees for the data structure’s operations. This should represent an upgrade over current hashing algorithms which do not allow for concurrent searching and mutating operations with hash tables. The result shows that this lock-free cuckoo hashing system performs consistently better than two efficient lock-based hashing algorithms, the chained and the hopscotch scenarios.
Pattern Discovery in White Etching Crack Experimental Data Using Machine Learning Techniques

White etching crack (WEC) failure is a failure mode that affects bearings in many applications, including wind turbine gearboxes, where it results in high, unplanned maintenance costs. WEC failure is unpredictable as of now, and its root causes are not yet fully understood. While WECs were produced under controlled conditions in several investigations in the past, converging the findings from the different combinations of factors that led to WECs in different experiments remains a challenge. This challenge is tackled in this paper using machine learning (ML) models that are capable of capturing patterns in high-dimensional data belonging to several experiments in order to identify influential variables to the risk of WECs. Three different ML models were designed and applied to a dataset containing roughly 700 high- and low-risk oil compositions to identify the constituting chemical compounds that make a given oil composition high-risk with respect to WECs. This includes the first application of a purpose-built neural network-based feature selection method. Out of 21 compounds, eight were identified as influential by models based on random forest and artificial neural networks. Association rules were also mined from the data to investigate the relationship between compound combinations and WEC risk, leading to results supporting those of previous analyses. In addition, the identified compound with the highest influence was proved in a separate investigation involving physical tests to be of high WEC risk. The presented methods can be applied to other experimental data where a high number of measured variables potentially influence a certain outcome and where there is a need to identify variables with the highest influence.
