Observations on some Actinoporellas (Chlorophyta, Polyphysaceae). Revision of the Jacques Emberger Collection. Part 1

On the occasion of the inventory of the J. Emberger Collection, specimens from the "Lower Cretaceous" (Valanginian and Hauterivian) of Algeria, which are referable to the genus Actinoporella (Gumbel in Alth) and which were earlier identified to its type-species A. podolica (Alth) by Conrad et al., are re-examined. They correspond to two discrete species, one of which could be a junior synonym of A. podolica, a synonymy that remains pending because it would require a new sampling at the original locality in western Ukraine some 140 years after the original specimens, now lost, were collected. Regarding their age ascription, they are Tithonian and/or Berriasian in age, i.e., latest Jurassic (sensu Oppel) in age, not earliest Cretaceous. In addition to these two Actinoporellas, a third discrete species, initially described as Clypeina nigra (Conrad & Peybernes), but later referred to the genus Actinoporella, is revised. New data justify its re-ascription to the genus Bakalovaella Bucur. Finally, it is now confirmed that both the Polyphysaceae and the modern Dasycladaceae derive from the Diploporaceae either directly or indirectly through the ancestral Dasycladaceae.
African American Cancer Disparities and Compassion

African American patients tend to have worse overall rates of cancer survival compared to white patients due to racial disparities in screening, diagnosis, and treatment management. In this paper, I explore this issue by looking at the racial disparities that emerge in screening, diagnosing, and treating various types of cancer. The implicit bias that is present when healthcare clinicians interact with African American patients influences the cancer survival rate for this population. One possible solution to address this problem would be to establish and practice medicine with an emphasis on compassion. A compassion-based model of medicine will allow for healthcare clinicians to prioritize their patients’ needs, setting aside their own assumptions and healthcare system priorities in the process. I advocate for two policy implications related to using a compassion-based model of medicine: 1) teaching and training healthcare clinicians the importance of compassionate care early on in medical education, and 2) implementation of guidelines for those already practicing to help them move toward compassionate care.

Pathways to Expert Performance in Soccer

In sport, deliberate practice theory has significantly impacted research on expertise and what has been known as talent/skill development. A wealth of data shows how practice volume distinguishes across groups that vary in their level of skill attained. This theory has led to models of skill development which vary in their emphasis on early or late engagement in deliberate practice and early engagement in play and diversified sport involvement as compared to practice. Deliberate practice theory has been widely studied in dynamic team sports, such as soccer. Here we review research from work we have conducted over the past six years, based on comparisons of highly elite male and female soccer players. We have evaluated prospectively and cross-sectionally, the developmental activities most related to successful transitions and adult success at the highest level of sport, as well as relations between these activities and technical and tactical skills development and indices of motivation. Our data show that successful, adult elite athletes, in the UK and Canada, are defined by what is termed the early engagement pathway. This is characterized by majority engagement in the chosen sport since early childhood, although not exclusive engagement, and engagement in relatively high volumes of self-directed play, in addition to high volumes of more formal, structured practice. We discuss issues with some of this research, including those related to measurement, and present ideas for future research based against the backdrop of the deliberate practice framework.
www.econstor.eu Identity and Redistribution

This paper models the interaction between individualsidentity choices and redistribution. Both redistributive policies and identity choices are endogenous, and there might be multiple equilibria. The model is applied to ethnicity and social class. In an equilibrium with high taxes, the poor identify as poor and favor high taxes. In an equilibrium with low taxes, at least some of the poor identify with their ethnic group and favor low taxes. The model has two main predictions. First, redistribution is highest when society is ethnically homogenous, but the e¤ect of ethnic diversity on redistribution is not necessarily monotonic. Second, when income inequality is low, an increase in income inequality might induce the poor to identify with their ethnic group and therefore favor lower taxes.
On the distinctiveness of observed oceanic raindrop distributions

Abstract. Representation of the drop size distribution (DSD) of rainfall is a key element of characterizing precipitation in models and observations, with a functional form necessary to calculate the precipitation flux and the drops' interaction with radiation. With newly available oceanic disdrometer measurements, this study investigates the validity of commonly used DSDs, potentially useful a priori constraints for retrievals, and the impacts of DSD variability on radiative transfer. These data are also compared with leading satellite-based estimates over ocean, with the disdrometers observing a larger number of small drops and significantly more variability in number concentrations. This indicates that previous appraisals of raindrop variability over ocean may have been underestimates. Forward model errors due to DSD variability are shown to be significant for both active and passive sensors. The modified gamma distribution is found to be generally adequate to describe rain DSDs but may cause systematic errors for high-latitude or stratocumulus rain retrievals. Depending on the application, an exponential or generalized gamma function may be preferable for representing oceanic DSDs. An unsupervised classification algorithm finds a variety of DSD shapes that differ from commonly used DSDs but does not find a singular set that best describes the global variability.
A Data Mining Approach to Identify Key Factors of Traffic Injury Severity

Seventy percent of the traffic crash fatalities of Iran happen on rural roads, and a significant proportion of the rural roads network of this country is constituted of the main two-lane, two-way roads. The purpose of this study is to identify the most important factors which affect injury severity of drivers involved in traffic crashes on these roads, so that by eliminating or controlling such factors an overall safety improvement can be accomplished. Using the Classification and Regression Tree (CART), one of the powerful data mining tools, the crash data pertaining to the last three years (2006-2008) were analyzed. The variable selection procedure was carried out on the basis of Variable Importance Measure (VIM) which is one of the CART method outputs. The results revealed that not using the seat belt, improper overtaking and speeding are the most important factors associated with injury severity. KEYWORDS: injury severity; traffic safety; data mining; Classification and Regression Trees (CART); Variable Importance Measure (VIM)
Dose‐linearity of the pharmacokinetics of an intravenous [14C]midazolam microdose in children

Drug disposition in children may vary from adults due to age‐related variation in drug metabolism. Microdose studies present an innovation to study pharmacokinetics (PK) in paediatrics; however, they should be used only when the PK is dose linear. We aimed to assess dose linearity of a [14C]midazolam microdose, by comparing the PK of an intravenous (IV) microtracer (a microdose given simultaneously with a therapeutic midazolam dose), with the PK of a single isolated microdose.
AN EXPLORATION OF LEADERSHIP IN THE CULTURAL CONTEXT OF SAUDI ARABIAN HIGHER EDUCATION

The influence of culture on leadership is an area of significance. While the contribution of research to cross-cultural leadership in industry and business sectors has been substantial, the same cannot be claimed with regard to Higher Education, and in particular, Saudi Arabian Higher Education. This research study addresses this significant gap and explores societal and organisational cultures, and their influence on University Deans’ leadership perceptions and practices. The research has been conducted in eight, main governmental universities under the Ministry of Education control. Qualitative data has been collected, involving interviews with fifteen university Deans, with data scrutinized by an interpretive thematic analysis. The study’s findings conceptualise the cultural influence on leadership in the context of Saudi Arabian higher education with nine distinct themes identified: the influence of societal culture, tensions between traditions and change, limitations in Deans’ leadership preparation, a centralised environment, strict regulations, the authority of top management, selection and promotion features, reputational factors, and human resources issues. Moreover, due to these factors, five culturally conditioned leadership practices were identified: a reliance on authority, a lack of motivation, limitations in Dean-subordinates’ relations, autocratic decision making and limitations of planning techniques. The research yields a number of contributions to the existing understanding of this area. This includes the impact of culture on leadership practice in this context, particularly cross-cultural leadership. Further, by answering the questions of what is needed for leaders to be effective, the research offers a new dimension for leadership effectiveness, which was extensively explored by considering what is needed by leaders to be effective.
SUICIDE IN TAIWAN'S SOCIETY

Taiwan is a modern industrialized megalopolis clinging to the fringes of the ancient Chinese culture. This tiny island has evolved from agricultural backwater status to global technological giant over the last few decades. Despite the economic prosperity and democratic reforms, social problems involving suicide additionally emerged, and suicide became one of the top ten major causes of death since 1982. In this paper, we have presented data on the occurrence of suicide in Taiwan between 1986 and 2007. We have explored the socio-cultural, religious and economic elements associated with suicide in Taiwan's society. We have also outlined certain measures to minimize the occurrence of suicide in Taiwan in the near future.
Difficulty Index, Discrimination Index and Distractor Efficiency in Multiple Choice Questions

Objective: Our first objective was to evaluate the quality of MCQs by analyzing difficulty index, discrimination index and distractor efficiency. Our second objective was to find out the association of MCQs having good difficulty and discrimination indices with distractor efficiency.Methodology: This cross-sectional study was conducted at department of Pathology, Islamabad medical and dental college. Midterm paper comprising of total 65 MCQs was assessed for difficulty index (DIF), discrimination index (DI) and distractor efficiency (DE). Data was entered in Microsoft Excel 2010 and SPSS 21. Quantitative variables were expressed as mean±SD. Qualitative variables were written as number and percentage. Independent t-test was applied to find out the association of DIF and DI with DE.Results: According to DIF, out of total 65, 53(81%) MCQs were in acceptable category, only 1(2%) MCQ was too difficult and 11(17%) were too easy. Regarding DI, total 34(62%) MCQs showed excellent discrimination tendency to distinguish low and high performer students. While 15(23%), 5(8%) and 11(17%) MCQs demonstrated good, acceptable and poor discrimination ability respectively. Out of total 260 distractors, 72% were functional and only 28% were non-functional. Total 16(25%) MCQs had zero non-functional distractor (NFDs), while 30(46%) and 16(25%) MCQs had 1 and 2 NFDs respectively. Only 3(5%) MCQs were with 3 or more NFDs. DE was significantly more (100%) in 1 difficult item as compared to 11 easy items in which DE was less (36.33%). However, DE in MCQs having poor and good DI was almost same.Conclusion: In this paper of Pathology, large number of MCQs have acceptable level of DIF (81%) and DI (83%). Distractor efficiency related to presence of zero or 1 NFD is 71%. Through item analysis, standardized MCQs having average DIF, high discrimination power with large number of functioning distractors can be developed. Thus it is an effective way to improve the validity of examination and to efficiently assess the student performance.
Predisposed to Volunteer? Personality Traits and Different Forms of Volunteering

In this article, we evaluate the psychological basis of different forms of volunteering. To date, our knowledge about the relationship between personality and volunteering as an important facet of the social fabric is limited. Applying the Five-Factor Model of Personality (Big Five), we scrutinize this relationship in a comprehensive manner. We consider formal and informal volunteering as well as online volunteering as a new form of social participation. Empirically, we analyze a representative population sample of Switzerland using logistic regression models. We find that extraversion is the most consistent driver of volunteering. The effects of the remaining traits differ across the forms of volunteering. Additional analyses indicate that situational factors may moderate these relationships.
A Review on the Use of Unmanned Aerial Vehicles and Imaging Sensors for Monitoring and Assessing Plant Stresses

Unmanned aerial vehicles (UAVs) are becoming a valuable tool to collect data in a variety of contexts. Their use in agriculture is particularly suitable, as those areas are often vast, making ground scouting difficult, and sparsely populated, which means that injury and privacy risks are not as important as in urban settings. Indeed, the use of UAVs for monitoring and assessing crops, orchards, and forests has been growing steadily during the last decade, especially for the management of stresses such as water, diseases, nutrition deficiencies, and pests. This article presents a critical overview of the main advancements on the subject, focusing on the strategies that have been used to extract the information contained in the images captured during the flights. Based on the information found in more than 100 published articles and on our own research, a discussion is provided regarding the challenges that have already been overcome and the main research gaps that still remain, together with some suggestions for future research.
Reciprocal Associations Among Symptom Levels of Disturbed Grief, Posttraumatic Stress, and Depression Following Traumatic Loss: A Four-Wave Cross-Lagged Study

Disturbed grief, operationalized as persistent complex bereavement disorder (PCBD), correlates with yet differs from posttraumatic stress disorder (PTSD) and depression symptoms. However, knowledge about temporal associations among these symptoms is limited. We aimed to enhance our understanding of the etiology of loss-related distress by examining temporal associations among PCBD, PTSD, and depression symptom levels. Dutch people (N = 172) who lost significant other(s) in a plane disaster completed questionnaires for PCBD, PTSD, and depression 11, 22, 31, and 42 months after the disaster. Cross-lagged analyses revealed that changes in PCBD symptom levels have a greater impact on changes in symptom levels of PTSD and depression than vice versa. Our findings contradict the notion that PTSD and depression symptoms should be addressed before grief in treatment. Pending replication of our findings in clinical samples, we tentatively conclude that screening and treatment of grief symptoms has potential value in preventing long-lasting distress.
Immunogenetics of new onset diabetes after transplantation in Kuwait

Introduction and aim: New onset diabetes after transplantation (NODAT) is a serious metabolic complication following kidney transplantation. Although beta-cell dysfunction is considered the main contributing factor in the development of this complication, its exact etiology is yet to be identified. We aimed to investigate NODAT among kidney transplant cohort in Kuwait with special stress on correlation between its risk factors and interferon gamma genotyping. Materials and methods: We surveyed 309 kidney transplant recipients from Hamed Al Essa Transplantation Centre, Kuwait. The participants were categorized into cohorts according to the development of NODAT diagnosed based on the American Diabetes Association guidelines. Statistical analyses were performed using SPSS software. We genotyped interferon gamma as the leading immunosignature for T lymphocyte. Results: No relationship between ethnicity and the development of NODAT was identified. However, there was a significant difference in age between cohorts. Younger patients demonstrated a lower rate of NODAT while, NODAT reached its maximum in 40–60-year age group. IFNG TT genotype was significantly associated with NODAT (p=0.005), while IFNG AA was considerably higher in the non-NODAT group. Conclusion: Beside the conventional contributing factors of NODAT, our results might represent a suitable platform for a larger cytokine and chemokine spectrum genotyping.
Future Treatment of Alzheimer Disease

Alzheimer’s disease is an age-related progressive neurodegenerative disorder. The two major neuropathologic hallmarks of Alzheimer’s disease (AD) are extracellular Amyloid beta (A β ) plaques and intracellular neurofibrillary tangles (NFTs). A number of additional pathogenic mechanisms, possibly overlapping with A β plaques and NFTs formation, have been described, including inflammation, oxidative damage, iron dysregulation, cholesterol metabolism. To date, only symptomatic treatments exist for this disease, all trying to counterbalance the neurotransmitter disturbance. To block the progression of the disease they have to interfere with the pathogenic steps responsible for the clinical symptoms, including the deposition of extracellular amyloid β plaques and intracellular neurofibrillary tangle formation, inflammation and stem cell. In this review, we discuss new potential disease-modi-fying therapies for AD that are currently being studied in phase I–III trials.
Impact of sandy soil physico-chemical properties towards urban lakes eutrophication and inorganic pollutant status

Variety of soil type in Malaysia has contributed to the difference of soil properties dissolved in the water and the concern of soil problem in Malaysia involving from laterite, sandy, acid sulfate and organic soil type that required monitoring action. The physico-chemical properties assessment tools that were used to evaluate the water sample area consist of pH, temperature, dissolved oxygen (DO), total suspended solids (TSS), chemical oxygen demand (COD), biological oxygen demand (BOD) and ammoniacal nitrogen(NH3-N). For heavy metals, 10 elements had been selected based on Malaysia Environmental Quality Report for further evaluation that consists of (Al, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, Pb). Physico chemicals properties for water were measured in situ and in the laboratory before calculated with WQI formula to define the water quality index classification. Further analysis was prepared by using ICP-MS and ANOVA for heavy metals assessment equally for soil and water. The result obtained by in situ experiment and laboratory showed the average of WQI for sandy soil in urban lake was in class IV as average that suitable only for irrigation and the status of water mostly were polluted as amount of the high value in BOD (81.62mg/L), COD (23.53mg/L) and NH3-N (0.44mg/L). The level of TSS was low ( 27.18mg/L) as sandy soil particle less influence for soil movement into the water. As for the result of heavy metals, the composition varied in water but several elements exceeded the natural level such as Al (0.07mg/L), Cr (0.3mg/L), Ni(0.11mg/L), Cu(0.02mg/L) and Pb (1.43mg/L) as responding to the character of porosity in sandy soil. Meanwhile, two significant elements were found in sandy soil which was Al(157.95mg/kg) and Fe(156.17 mg/kg) and becomes a signature indicator. As a conclusion, evaluation influence of sandy soil physico-chemicals properties of water and heavy metals concentration are significant for water quality monitoring action to minimize water quality degradation in Malaysia.
Examining the Indirect Effects of Self-Concept on Work Readiness Through Resilience and Career Calling

The current study examined the relations among self-concept, career calling, resilience, and work readiness in a Malaysian sample of vocational college students (N = 674). As hypothesized, self-concept was positively associated with work readiness. To explain this relation further, we examined the indirect effect of self-concept through calling and resilience on work readiness. Using structural equation modeling, both career calling and resilience were found to be significant avenues through which self-concept influences work readiness. Results of the indirect effects also indicated that resilience was a stronger pathway compared to career calling. These results suggest that for vocational college students, a more crystallized self-concept may link to greater work readiness skills due, in part, to a heightened sense of resilience and clarity in one’s career calling.
Pleistocene climate changes, and not agricultural spread, accounts for range expansion and admixture in the dominant grassland species Lolium perenne L.

Grasslands have been pivotal in the development of herbivore breeding since the Neolithic and still represent the most widespread agricultural land use across Europe. However, it remains unclear whether the current large‐scale genetic variation of plant species found in natural grasslands of Europe is the result of human activities or natural processes.
