Dynamical Complexity and Regularity

The aim of this paper is to provide a mathematical basis for the plausible idea that regular dynamical laws can only produce (quickly and reliably) regular structures. Thus the actual laws, which are regular, can only produce regular objects, like crystals, and not irregular ones, like living organisms. 1. The dynamical complexity of an object is defined. This is something like its algorithmic information content, but I use a dynamical system in place of a universal Turing machine. A dynamically-complex object is, roughly speaking, one that the dynamical laws have little or no tendency to produce from a random initial state. A “GIGO” theorem is proved, that an object with dynamical complexity n bits requires time 2 n to be generated, so that highly-complex objects effectively cannot be generated spontaneously. 2. The term “regular dynamical law” is defined, in such way that the known dynamical laws of physics are regular. The irregularity of an object is defined, and then I try to show that the dynamical complexity of an object s, with respect to a regular law, always exceeds the irregularity of s. It seems clear that living organisms are highly irregular, in the sense defined, so (if this result holds) they must be dynamically complex as well. It would then follow that living organisms could not have been produced, from a random initial state, by the known dynamical laws.
Is Littoral Habitat Affected by Residential Development and Land Use in Watersheds of Wisconsin Lakes?

ABSTRACT We measured differences in nearshore littoral zone habitat among lakes with different amounts of residential development and different patterns of watershed land use. Sampling stations were located at randomly selected sites within the nearshore littoral zone of limnologically similar lakes. An index of development density (based on counts of residential structures) and watershed cover types detected by satellite imagery summarized human influence in the riparian zone and watershed. To compare effects of development at local sites to effects of cumulative development density (structures/km shoreline), we used analysis of covariance. Quantity of woody debris, emergent vegetation and floating vegetation decreased at developed sites and in lakes with greater cumulative lakeshore development density. Littoral sediments contained more fine particles at developed sites and in lakes with greater development density. Sediment composition, quantity of vegetation, and woody debris were weakly associated with differences in watershed land use. Cumulative changes to watersheds and riparian zones are associated with measurable differences in littoral habitat that may not be detectable at smaller scales. For effective conservation, regulatory programs should consider the cumulative effects of development and land use on aquatic systems.

The Hidden Cost of Being African American: How Wealth Perpetuates Inequality

Over the past three decades, racial prejudice in America has declined significantly and many African American families have seen a steady rise in employment and annual income. But alongside these encouraging signs, Thomas Shapiro argues in The Hidden Cost of Being African American, fundamental levels of racial inequality persist, particularly in the area of asset accumulation--inheritance, savings accounts, stocks, bonds, home equity, and other investments-. Shapiro reveals how the lack of these family assets along with continuing racial discrimination in crucial areas like homeownership dramatically impact the everyday lives of many black families, reversing gains earned in schools and on jobs, and perpetuating the cycle of poverty in which far too many find themselves trapped. Shapiro uses a combination of in-depth interviews with almost 200 families from Los Angeles, Boston, and St. Louis, and national survey data with 10,000 families to show how racial inequality is transmitted across generations. We see how those families with private wealth are able to move up from generation to generation, relocating to safer communities with better schools and passing along the accompanying advantages to their children. At the same time those without significant wealth remain trapped in communities that don't allow them to move up, no matter how hard they work. Shapiro challenges white middle class families to consider how the privileges that wealth brings not only improve their own chances but also hold back people who don't have them. This "wealthfare" is a legacy of inequality that, if unchanged, will project social injustice far into the future. Showing that over half of black families fall below the asset poverty line at the beginning of the new century, The Hidden Cost of Being African American will challenge all Americans to reconsider what must be done to end racial inequality.
The Ebola Virus VP35 Protein Is a Suppressor of RNA Silencing

RNA silencing or interference (RNAi) is a gene regulation mechanism in eukaryotes that controls cell differentiation and developmental processes via expression of microRNAs. RNAi also serves as an innate antiviral defence response in plants, nematodes, and insects. This antiviral response is triggered by virus-specific double-stranded RNA molecules (dsRNAs) that are produced during infection. To overcome antiviral RNAi responses, many plant and insect viruses encode RNA silencing suppressors (RSSs) that enable them to replicate at higher titers. Recently, several human viruses were shown to encode RSSs, suggesting that RNAi also serves as an innate defence response in mammals. Here, we demonstrate that the Ebola virus VP35 protein is a suppressor of RNAi in mammalian cells and that its RSS activity is functionally equivalent to that of the HIV-1 Tat protein. We show that VP35 can replace HIV-1 Tat and thereby support the replication of a Tat-minus HIV-1 variant. The VP35 dsRNA-binding domain is required for this RSS activity. Vaccinia virus E3L protein and influenza A virus NS1 protein are also capable of replacing the HIV-1 Tat RSS function. These findings support the hypothesis that RNAi is part of the innate antiviral response in mammalian cells. Moreover, the results indicate that RSSs play a critical role in mammalian virus replication.
Search Cost Reduction Increases Variation In Hotels Occupancy Rate: A Theoretical And Empirical Analysis

This study explores how direct online booking affects the variation in hotel bed-places occupancy rate between peak and off-peak periods, thereby contributing to three strands of literature, respectively the determinants of seasonality, the tourist information acquisition process and the impact of the internet on tourism. The empirical analysis, covering 18 countries over the 1997-2007 period, investigates the impact of an increase in the use of the internet by consumers on the seasonal variation in the occupancy rate. We find that internet actually increases the variation in occupancy. We contribute to reduce the lack of a theoretical framework in this field by developing a formal model to illustrate why and how the reduction in search cost entailed by the use of the internet can indeed lead to a higher seasonality.
Small-angle scattering and morphologies of ultra-flexible microemulsions1

Three-component fluids can exhibit structured density fluctuations, and their small-angle scattering patterns present similarities to those of classical microemulsions. One general analytical expression with two additive contributions (one for the two immiscible fluids and a smaller one for a structured fluid) allows the whole phase diagram to be mapped in the single-phase domain.
IDH/MGMT-driven molecular classification of low-grade glioma is a strong predictor for long-term survival.

BACKGROUND Low-grade gliomas (LGGs) are rare brain neoplasms, with survival spanning up to a few decades. Thus, accurate evaluations on how biomarkers impact survival among patients with LGG require long-term studies on samples prospectively collected over a long period. METHODS The 210 adult LGGs collected in our databank were screened for IDH1 and IDH2 mutations (IDHmut), MGMT gene promoter methylation (MGMTmet), 1p/19q loss of heterozygosity (1p19qloh), and nuclear TP53 immunopositivity (TP53pos). Multivariate survival analyses with multiple imputation of missing data were performed using either histopathology or molecular markers. Both models were compared using Akaike's information criterion (AIC). The molecular model was reduced by stepwise model selection to filter out the most critical predictors. A third model was generated to assess for various marker combinations. RESULTS Molecular parameters were better survival predictors than histology (ΔAIC = 12.5, P< .001). Forty-five percent of studied patients died. MGMTmet was positively associated with IDHmut (P< .001). In the molecular model with marker combinations, IDHmut/MGMTmet combined status had a favorable impact on overall survival, compared with IDHwt (hazard ratio [HR] = 0.33, P< .01), and even more so the triple combination, IDHmut/MGMTmet/1p19qloh (HR = 0.18, P< .001). Furthermore, IDHmut/MGMTmet/TP53pos triple combination was a significant risk factor for malignant transformation (HR = 2.75, P< .05). CONCLUSION By integrating networks of activated molecular glioma pathways, the model based on genotype better predicts prognosis than histology and, therefore, provides a more reliable tool for standardizing future treatment strategies.
If You Wish to Change the World, Start with Yourself

During the past ten years, requirements on functionality of business applications have been slowly changing. This shift consists of moving from traditional command based applications to inherently interactive applications of workflow and groupware type. For modeling new kind of business applications, the authors suggest an approach to defining interaction that is not based on explicit communication. In this approach, interaction is realized via active relationships that can propagate changes from one object to another. Based on this idea, which comes from the previous research work of the authors, the paper discusses the issues of introducing “harnesses” on the interactive behavior, finding the right place for the end-users in the model, and modeling distribution of tasks between different users.
Mechanical Theorem-Proving by Model Elimination

A proof procedure based on a theorem of Herbrand and utilizing the matching technique of Prawitz is presented. In general, Herbrand-type proof procedures proceed by generating over increasing numbers of candidates for the truth-functionally contradictory statement the procedures seek. A trial is successful when some candidate is in fact a contradictory statement. In procedures to date the number of candidates developed before a contradictory statement is found (if one is found) varies roughly exponentially with the size of the contradictory statement. (“Size” might be measured by the number of clauses in the conjunctive normal form of the contradictory statement.) Although basically subject to the same rate of growth, the procedure introduced here attempts to drastically trim the number of candidates at an intermediate level of development. This is done by retaining beyond a certain level only candidates already “partially contradictory. ” The major task usually is finding the partially contradictory sets. However, the number of candidate sets required to find these subsets of the contradictory set is generally much smaller than the number required to find the full contradictory set.
The Drosophila Fragile X Mental Retardation Gene Regulates Sleep Need

Sleep need is affected by developmental stage and neuronal plasticity, but the underlying mechanisms remain unclear. The fragile X mental retardation gene Fmr1, whose loss-of-function mutation causes the most common form of inherited mental retardation in humans, is involved in synaptogenesis and synaptic plasticity, and its expression depends on both developmental stage and waking experience. Fmr1 is highly conserved across species and Drosophila mutants carrying dFmr1 loss-of-function or gain-of-function mutations are well characterized: amorphs have overgrown dendritic trees with larger synaptic boutons, developmental defects in pruning, and enhanced neurotransmission, while hypermorphs show opposite defects, including dendritic and axonal underbranching and loss of synapse differentiation. We find here that dFmr1 amorphs are long sleepers and hypermorphs are short sleepers, while both show increased locomotor activity and shortened lifespan. Both amorphs and hypermorphs also show abnormal sleep homeostasis, with impaired waking performance and no sleep rebound after sleep deprivation. An impairment in the circadian regulation of sleep cannot account for the altered sleep phenotype of dFmr1 mutants, nor can an abnormal activation of glutamatergic metabotropic receptors. Moreover, overexpression of dFmr1 throughout the mushroom bodies is sufficient to reduce sleep. Finally, dFmr1 protein levels are modulated by both developmental stage and behavioral state, with increased expression immediately after eclosure and after prolonged wakefulness. Thus, dFmr1 expression dose-dependently affects both sleep and synapses, suggesting that changes in sleep time in dFmr1 mutants may derive from changes in synaptic physiology.
Teaching and learning primary science

This new edition is revised and updated to take account of the profound changes in primary school science teaching over recent years. The author provides a sound theory-based perspective on school and classroom practice in science, based on a belief that decisions about the curriculum and its implementation in teaching should be based on a clear view of the kind of learning that is intended. The notion of the 'kind of learning' embraces both the way children learn and what they learn, both of which are dependent on the role of the teachers and the organization of the school. In the revision, the author has given attention to the development of learners' ideas in science and to the role of process skills and attitudes in learning with understanding. All aspects of the teacher's active role in providing opportunities, for all learners to develop ideas, skills and attitudes are discussed in practical terms, with many examples. Theoretical and practical aspects of assessment and record-keeping are covered in two new chapters and the section on evaluation of provision has been largely rewritten. This Second Edition is an essential resource for teachers with responsibility for or special interest in science, for advisers, teacher educators and all concerned with curriculum and professional development

The Reliability and Validity of Short Online Questionnaires to Measure Fruit and Vegetable Intake in Adults: The Fruit Test and Vegetable Test

The first aim of this study was to investigate the stability of the Fruit Test and Vegetable Test over time and whether the Fruit Test and Vegetable Test are capable of measuring fruit and vegetable intake with consistency. Second, the study aimed to examine criterion (concurrent) validity of the Fruit Test and Vegetable Test by testing their agreement with 7-day food diary-derived measures of fruit and vegetable intake. In total 58 adults (31% male, mean age = 30.0±12.09y) completed the Flemish Fruit and Vegetable test by indicating the frequency of days that they ate fruit and vegetables and the number of portions during the past week. Validity was tested by using a 7-day food diary as a golden standard. Adults were asked to register their fruit and vegetable intake daily in a diary during one week. Spearman correlations were measured to compare total intake reported in the Fruit and Vegetable Test and in the 7-day diary. Agreement plots were used to illustrate absolute agreement. Test-retest reliability was evaluated by having participants completing the Fruit Test and Vegetable Test twice. The Fruit Test (ICC = 0.81) and Vegetable Test (ICC = 0.78) showed excellent and substantial reliability. The Fruit Test (ρ = 0.73) and Vegetable Test showed good validity. Agreement plots showed modest variability in differences between vegetable and fruit intake as measured by the Vegetable and Fruit Test and the 7-day food diary. Also a small underestimation of fruit intake in the Fruit test and vegetable intake in the Vegetable test against the 7-day food diary was shown. Based on the results, it is suggested to include portion size pictures and consumption of mixed vegetables to prevent underestimation. To prevent overestimation, it is concluded to add a moderate number of representative fruit and vegetable items, questions on portion size, household sizes with sufficient detail and food items highly tailored to the dietary behaviors and local food items of the population surveyed. The questionnaires can easily be adapted for the use in other diets (e.g. Asian diet), but reliability and validity should then be examined again. Also, validity remains to be tested in other population groups (i.e. low socio economic status groups, other age groups).
Lily Cultivars Have Allelopathic Potential in Controlling Orobanche aegyptiaca Persoon

As a devastating holoparasitic weed, Orobanche aegyptiaca Persoon. (Egyptian broomrape) causes serious damage to agricultural production and threatens economic development, which has raised widespread concern. The present study was conducted to determine whether lilies have the potential to be used as ‘trap crops’ for controlling O. aegyptiaca Persoon. In the experiments, the ability of three popular lily cultivars (Lilium Oriental hybrids ‘Sorbonne’, Lilium LA (Longiflorum hybrids x Asiatic hybrids) hybrids ‘Ceb Dazzle’, and Lilium Longiflorum hybrids (L. formosanum x L. longiflorum) ‘L. formolongo’) to induce O. aegyptiaca Persoon. seed germination was assessed. Parts of the three lily cultivars, including the rhizosphere soil and underground and above-ground organs, all induced “suicidal germination” of parasitic O. aegyptiaca Persoon. seed at four growth stages. Specifically, Sorbonne and Ceb Dazzle behaved with similar allelopathy, and the bulb, scale leaf and aerial stem exhibited stronger allelopathic effects on O. aegyptiaca Pers. germination compared to other organs. Aqueous L. formolongo leaf extracts may contain more stable, effective stimulants given that they induced the highest germination rate at 76.7% even though the extracts were serially diluted. We speculate that these organs may be advantageous in further isolating and purifying economical active substances that can be substitutes for GR24. These results indicate that lilies have the potential to be used as a trap crops or can be processed into green herbicide formulations that can be applied in agriculture production to rapidly deplete the seed bank of O. aegyptiaca Persoon. parasitic weeds in soil.
Corporate social responsibility disclosures and earnings quality: Are they a reflection of managers’ opportunistic behavior?

Purpose - – This paper aims to explore the relationship between corporate social responsibility (CSR) disclosures and earnings quality proxied by earnings accruals. Specifically, we examine whether CSR disclosures are context-specific, that is, whether companies dominated by powerful stakeholders are obliged to behave in a responsible manner to constrain earnings management, thereby reporting higher-quality earnings to investors. Design/methodology/approach - – This paper explores the relationship between CSR disclosures and earnings quality proxied by earnings accruals. Specifically, we examine whether CSR disclosures are context-specific, that is, whether companies dominated by powerful stakeholders are obliged to behave in a responsible manner to constrain earnings management, thereby reporting higher-quality earnings to investors. Findings - – Results show that managers in an emerging economy manage earnings when they provide more CSR disclosures. Such earnings management is achieved through income increasing discretionary accruals. Furthermore, companies from export-oriented industries dominated by powerful stakeholders (international buyers) disclosing more CSR activities, provide transparent financial reports through constraining earnings management. Originality/value - – The findings of this study are significant for both investors and policymakers. Investors should not take for granted that firms engage in CSR activities, behave ethically and provide transparent financial reports. As we document that firms might manipulate earnings through discretionary accruals and provide less transparent financial reports to shareholders, the credibility of firms’ CSR policies should be assessed with caution. Policies directing at promoting socially responsible practices instead of motivating the desired behaviour, may provide managers with additional incentives to utilise CSR for opportunistic behaviour. Thus, policymakers need to be cautious about this opportunistic behaviour and enhance monitoring to enforce social compliance. Possibly, some guidelines can be introduced to confirm that CSR disclosures are based on actual practice and not just a “green wash” statement to deceive stakeholders.
Comparison of Medicaid nursing home payment systems

This article summarizes the main findings of a study comparing three generic Medicaid nursing home payment systems: case-mix, facility-specific, and class-rate. The major comparative analyses examined patient-level case mix and quality, facility-level costs, Medicaid payment rates, and profitability. The study also analyzed case-mix payment systems in greater detail, emphasizing the earlier systems. The results suggest advantages and disadvantages for all system types and highlight important considerations for policyplanners, particularly in States considering case-mix systems. The article concludes with a discussion of issues important to further research on nursing home payment.
