description: The goal of this thesis was to reposition individual preparedness within a social environmental context. First, a theoretical model was developed to more accurately represent the social environmental considerations neglected in current preparedness research and policy. A series of three studies tested this model using a mixed-methods approach: First, subjective conceptualizations of preparedness were explored in a qualitative analysis (N = 12). Findings revealed that participants evaluated their readiness not in terms of prescribed activities, but perceptions about their current resourcefulness as well as past local hazards. Participants’ had positive social environments which also reinforced their perceived coping ability in future emergency events. Subsequent thesis studies investigated the role social environment further, using quantitative data. The second study explicitly tested whether perceptions of risk and coping could explain differences in preparedness based on demographic attributes linked to variations in social environment. Data from a survey examining Canadians perceptions regarding terrorism threats (N = 1503) revealed that greater anticipated response was significantly associated with increased age, as well as female gender, higher education levels, and higher income levels. Statistically significant differences in threat appraisals were also reported based on these demographic groupings. However, mediation analyses demonstrated that with the exception of gender, differences in anticipated response could not be explained via risk perceptions or perceived coping efficacy, suggesting that social environment’s role in preparedness is not related to the internal processes often targeted in current campaigns. The third study used a multilevel design to investigate the contextual role of neighbourhood social environment in anticipated emergency response. Results demonstrated that a more deprived social neighbourhood context was related to lowered anticipated emergency response. This relationship was maintained after controlling for significant individual-level factors such as previous experience and sociodemographics, highlighting the importance of neighbourhood social context in facilitating emergency preparedness. Taken together, these findings provide novel evidence that focusing preparedness strategies to primarily target internal processes is misguided, and that future research and policy must position preparedness efforts in the context of existing social environmental resources and barriers in order to build capacity for effective emergency response.

description: July temperature (TJUL) and total annual precipitation (ANNP) are reconstructed to better understand the spatial and temporal patterns of change in North America over the last 2,000 years using pollen databases. Using a customized application in R, the reconstructions use a composite averaging of multiple site reconstructions that show a distinct warmer Medieval Warm Period (MWP) compared to the colder Little Ice Age (LIA). Results show that, both multi-centennial scale periods are re- constructed as cooler than the last 50 years. Regional time series from several forested ecoregions show positive anomalies up to 0.6ºC during the MWP and anomalies up to -0.3ºC during the LIA. In order to test whether the TJUL reconstructions are biased to the modern calibration climate data, we show a distinct difference between the reconstructions when using station versus reanalysis-based modern TJUL fields. Reconstructions using station-based modern calibration data sets better reflect the centennial to multi-centennial scale climate variability as compared to the reanalysis-based modern calibration data sets that reveal a warm-bias. We justify the choice of the Whitmore et al. (2005) modern data set for large-scale pollen-based paleoclimate reconstructions. Finally we use Local Indicators of Spatial Association (LISA) to spatially filter the ANNP reconstructions in order to distinguish regional hydroclimate patterns from local site-specific conditions. Results show that a La Nina, positive North Atlantic Oscillation (+NAO) and positive Atlantic Multidecadal Oscillation (+AMO) state-like dominated both the MWP and Roman Warm Period (RWP), although the MWP was generally drier. In contrast, the Dark Ages Cold (DAC) period was likely dominated by El Nino, negative NAO and negative AMO state-like circulation. Minimum solar and high volcanic activity is likely to have contributed to more complex hydroclimate regional patterns during the LIA. The results presented in this dissertation can be used as benchmark data sets for future climate data-model comparisons in order to improve our understanding of natural climate variability during the past 2,000 years in the context of modern human-induced climate change.

description: Newts have the incredible ability to regenerate many different organs and tissues as adults, including the limbs. Limb regeneration occurs via the dedifferentiation of stump tissue and the formation of a blastema, which provides the majority of cells for the regenerate. Despite all that we have learned about dedifferentiation and blastema formation, the cellular and molecular mechanisms underlying these processes are still poorly understood. We used representational difference analysis (RDA) to identify genes involved in the early dedifferentiation process in newt forelimb regeneration. Our analysis identified approximately 410 unique genes that were differentially regulated during this process. Microarray analysis was used to determine the expression profile of these genes throughout limb and tail regeneration. We used quantitative PCR (qPCR) to validate the expression of a subset of these genes [β-catenin, wntless, dapper, thymosin-β 4 (Tβ4), and thymosin-β 10/15 (Tβ10/15)] in regenerating limb and tail tissue, as well as in differentiating newt myoblasts. We also verified the expression of these genes in the regenerating newt limb using immunohistochemistry (IHC) and in situ hybridization (ISH). Finally, we performed a functional analysis on β-catenin, wntless, dapper, and Tβ4 by overexpressing these genes in mouse myoblasts to examine their effects on differentiation and potential roles in dedifferentiation. Quantitative PCR verified the expression of β-catenin, wntless, dapper, and Tβ4 during limb regeneration and IHC/ISH localized the β-catenin and Tβ4 proteins to the blastema during regeneration. Tβ10/15 was shown by qPCR to be expressed in the tail during regeneration. Overexpression of newt β-catenin, wntless, dapper, and Tβ4 in mouse myoblasts showed that each of these genes has an inhibitory effect on the differentiation of myoblasts into myotubes and, therefore, may play a role in promoting or maintaining the dedifferentiated state. Our work has identified a large number of genes with potential roles in regulating the dedifferentiation process during newt forelimb regeneration. We have also laid a framework from which much more work can be done by drawing on the genes we have identified and the microarray data, which indicate ideal follow-up candidates. Our analysis of specific genes has also increased our understanding of the molecular events occurring during the dedifferentiation process in the regenerating newt limb.
Interfacial superconductivity in Cu/Cu$_{\rm{2}}$O and its effect on shielding ambient electric fields

description: A model is presented for two-dimensional superconductivity at semiconductor-on-metal interfaces mediated by Coulomb interactions between electronically-active interface charges in the semiconductor and screening charges in the metal. The junction considered is native Cu$_{\rm{2}}$O on Cu in which an interfacial double charge layer of areal density $n$, comprising superconducting holes in Cu$_{\rm{2}}$O and mediating electrons in Cu, is induced in proportion to a sub-monolayer of adsorbed $^{\rm{4}}\rm{He}$ atoms. Evidence for superconductivity on copper with prior air exposure is revealed in new analysis of previously published work function data. Based on a theory developed for layered superconductors, the intrinsic transition temperature $T_{\rm{C}}$ = $β$ $n$$^{\rm{1/2}}$/$ζ$ is determined by $n$ and transverse distance $ζ$ $\simeq$ 2.0 $\rm{Å}$ between the charge layers; $β$ = 1.933(6) $e$$^{\rm{2}}$$\barλ$$_{\rm{C}}$/k$_{\rm{B}}$ = 1247.4(3.7) K-$\rm{Å}$$^{\rm{2}}$ is a universal constant involving the reduced Compton wavelength of the electron $\barλ$$_{\rm{C}}$. This model is applied to understanding the shielding of copper work-function patch and gravitational compression electric fields reported in the Witteborn-Fairbank gravitational electron free fall experiment. Interfacial superconductivity with $n$ $\simeq$ 1.6 $\times$ 10$^{\rm{12}}$ $\rm{cm}^{\rm{-2}}\rm{,}$ $T_{\rm{C}}$ $\simeq$ 7.9 K and Berezinskiĭ-Kosterlitz-Thouless temperature $T_{\rm{BKT}}$ $\simeq$ 4.4 K accounts for the shielding observed at temperature $T$ $\simeq$ 4.2 K. Helium desorption and concomitant decreases in $n$ and $T_{\rm{C}}$ replicate the temperature transition in ambient electric fields on falling electrons, as observed by Lockhart et al., and the vanishing of superconductivity above $T$ $\simeq$ 4.8 K.

description: Background: Depression is a major health concern and self-management of depressive symptoms using patient-initiated strategies has the potential to reduce the burden of this condition. A better understanding of behaviour change related to these patient-initiated strategies is needed. Method: This randomized controlled trial study used an online survey and Knowledge Translation and Transfer theory-based educational intervention to examine the Theory of Planned Behavior model in the context of nine patient-initiated strategies for the self-management of depression and low mood. Results: Perceived Behavioural Control was identified as the single greatest predictor of Intentions to engage in strategies. Attitudes predicted Intentions to a lesser degree. Subjective Norms were not identified as unique predictors. Theory of Planned Behavior antecedent variables together explained over one third of the variance in Intentions. Intentions to engage in patient-initiated strategies were shown, in some cases, to significantly predict actual engagement in strategies. Level of depressive symptoms did not meaningfully impact any of the antecedent variables or Intentions. Results also suggest that an educational intervention based on Knowledge Translation and Knowledge Transfer principles significantly improved both Attitudes and Subjective Norms – Physician towards patient-initiated strategies. Perceived Behavioural Control and Intentions were not improved as a result of the educational intervention. Theoretical Conclusions: Findings suggest that the Theory of Planned Behavior functions well in the context of patient-initiated strategies for depression and low mood. Perceived Behavioural Control was identified as the greatest predictor of Intentions to engage in patient-initiated strategies. Results also suggest mood difficulties are not captured by the model’s antecedent variables but instead should be included as an additional variable in this model. The findings of the current study support an integrated model of Knowledge Translation and Transfer and Theory of Planned Behavior. Practical Conclusions: The current study’s findings provide a better understanding of behaviour change in the context of patient-initiated strategies and will help guide interventions aimed at improving engagement in these behaviours. Findings also provide support and recommendations for the use of Knowledge Translation and Transfer theory-based educational interventions to improve self-management of depression and low mood.

description: Purpose: There has been a call to improve measurement rigour and standardization of food parenting practices measures, as well as aligning the measurement of food parenting practices with the parenting literature. Drawing from an expert-informed conceptual framework assessing three key domains of food parenting practices (autonomy promotion, control, and structure), this study combined factor analytic methods with Item Response Modeling (IRM) methodology to psychometrically validate responses to the Food Parenting Practice item bank. Methods: A sample of 799 Canadian parents of 5–12-year-old children completed the Food Parenting Practice item bank (129 items measuring 17 constructs). The factorial structure of the responses to the item bank was assessed with confirmatory factor analysis (CFA), confirmatory bi-factor item analysis, and IRM. Following these analyses, differential Item Functioning (DIF) and Differential Response Functioning (DRF) analyses were then used to test invariance properties by parents’ sex, income and ethnicity. Finally, the efficiency of the item bank was examined using computerized adaptive testing simulations to identify the items to include in a short form. Results: Overall, the expert-informed conceptual framework was predominantly supported by the CFA as it retained the same 17 constructs included in the conceptual framework with the exception of the access/availability and permissive constructs which were respectively renamed covert control and accommodating the child to better reflect the content of the final solution. The bi-factor item analyses and IRM analyses revealed that the solution could be simplified to 11 unidimensional constructs and the full item bank included 86-items (empirical reliability from 0.78 to 0.96, except for 1 construct) and the short form had 48 items. Conclusion: Overall the food parenting practice item bank has excellent psychometric properties. The item bank includes an expanded version and short version to meet various study needs. This study provides more efficient tools for assessing how food parenting practices influence child dietary behaviours. Next steps are to use the IRM calibrated item bank and draw on computerized adaptive testing methodology to administer the item bank and provide flexibility in item selection.

description: Radical chemistry is a crucial tool to organic chemists. Recent trends in the field have been directed towards the development of photocatalysts capable of generating a radical through a renewable source like sunlight using a single electron transfer mechanism. The use of Au2dppm2Cl2, having a stronger reducing potential, allows an expansion of the reactivity to those achieved by iridium and ruthenium catalysts.1 The focus of this thesis is axed on the development of Au2dppm2Cl2 as an efficient photoredox catalyst for a tandem one-pot catalysis and its application in a dual catalytic system. The use of Au2dppm2Cl2 in a dual catalysis for the synthesis of β-amino acids was undertaken. The problems encountered over the course of the investigation showed an insufficient oxidation potential of the photoredox catalyst in addition to the facile homolytic cleavage of the C-halogen bond under UV light. However, this shows great promise for the achievement of beta amino acids using solely organocatalysis. The development of a tandem one-pot radical cyclization for the synthesis of fused- carbocycles, which are frequently encountered scaffolds in diterpenoid natural products, is reported. The initial experiments were conducted on a model substrate, enabling the verification of the proposed hypothesis. The success of this methodology was then applied to various substrates affording the desired fused 5 membered rings in good yields. These reactions show tremendous potential in the field of total synthesis for the rapid access of complex molecular structures. (1) Revol, G.; McCallum, T.; Morin, M.; Gagosz, F.; Barriault, L.

description: La recension des écrits tend à démontrer que la mise en œuvre réussie de la décentralisation dépend de l’appropriation du changement par les principaux acteurs. La présente étude exploratoire et qualitative vise à explorer l’appropriation de la réforme de décentralisation auprès des cadres scolaires du ministère des enseignements secondaires et supérieur du Burkina Faso. L’analyse a porté sur la manière dont les participants intègrent les « réalités substantielles » de la décentralisation dans leur gestion quotidienne et s’attache à répondre à la question suivante : Comment les directeurs régionaux et les chefs d’établissements secondaires publics du Burkina Faso s’approprient leurs prérogatives et actualisent leurs pratiques de gestion ? Le but de la recherche étant de comprendre le vécu et le ressenti des cadres scolaires, la collecte des données s’est faite selon diverses techniques qualitatives, entrevue semi-directive, observation et collecte de documents d’archives, auprès de huit participants. L’analyse des données a permis de découvrir que les participants adhèrent aux réformes de décentralisation. Ils perçoivent de façon pertinente leur démarche appropriative. Les principaux aspects liés à l’appropriation du changement se rapportent à : a) une bonne connaissance des textes, des personnes et de soi; b) un développement de nouvelles compétences et attitudes; c) et un ajustement perpétuel aux exigences nouvelles et au contexte. Il ressort de l’analyse comparée de l’appropriation et de la mise en œuvre de la décentralisation des récurrences convergentes et divergentes entre les participants. De façon plus détaillée, les résultats indiquent que leur démarche appropriative est sous-tendue par des facteurs individuels, législatifs et contextuels. Cette recherche contribue également à informer le monde scientifique et les décideurs politiques sur les difficultés qu’éprouvent les cadres scolaires en matière de gestion et d’appropriation du changement. À cet égard, elle retrace la manière dont les participants à l’étude y font face.

description: Robert Thornton of East Newton, Yorkshire (c.1367-c.1465) is the most important scribe of late-medieval England: the only amateur scribe we know to be responsible for the concurrent production of multiple manuscript anthologies. This project constitutes the first extended study devoted exclusively to Robert Thornton and his books that treats them both as independent and as in conversation with each other. By uniting the concerns of codicology and cultural history, we can gain new insights into the effect of each manuscript’s textual sequences while also considering the effect of the distribution of texts among both manuscripts. Moreover, by examining Thornton’s romances in their original material and social contexts, we can read them as they would have been encountered by Thornton and his intended readers, and gain insight into the social and cultural anxieties that may have led to their organization and distribution among his two books. Chapter 1 compares Thornton’s compilations to those of analogous manuscripts, and demonstrates that Thornton took a more active role than most contemporary compilers did in rearranging and editing his texts in order to emphasize shared themes and interests within his books. Chapters 2 and 3 of this dissertation examine the nature of each of Thornton’s manuscripts in turn. Chapter 2 demonstrates that Lincoln Cathedral Library MS 91 is a book meant to be used in the maintenance of social, spiritual, and physical health, written to be a useful tool for as wide a range of people as possible. Chapter 3 demonstrates that British Library MS Additional 31042 is a history book that traces the development of Christian civilization from its beginnings in the Holy Land to its present form in Thornton’s England. This dissertation then assesses Thornton’s whole library. Chapter 4 examines the literary contexts of Thornton’s romances, demonstrating that they are divided into thematic groups that emphasise conflict between the interests of individuals and the interests of the individual and communal identities with which they associate. Chapter 5 examines the social context of Thornton’s romances, demonstrating that Thornton employs the discourse of English nationalism produced during the Council of Constance (1414-1418), and that he therefore distributed his romances in order to emphasize England’s superiority to France.

description: There is a void of existing measures assessing young adults’ perceptions of childhood disorganized and controlling attachment. The current research project aimed to fill this gap by developing a convenient self-report measure, the Childhood Disorganization and Role Reversal Scale (CDRR: Meier & Bureau, 2012), which comprehensively assesses for the complexity of those attachment constructs in young adults. The CDRR is a novel measure as it assesses the unique attachment representations of mother-child and father-child relationships. This research project had three main objectives. The first objective was the development of the CDRR. It was guided by the recommendations of various scholars in scale development using classical measurement theory. The items of the CDRR were informed by the attachment and family systems literature. The factor structure of the CDRR was determined through conducting principal components analyses (PCA). The second objective, constituting Study 1, aimed to assess the psychometric properties of the CDRR, namely, its structural stability, internal reliability, temporal reliability, convergent and discriminant validity and criterion-related validity. Lastly, the third objective, involving Study 2, sought to provide further support for the validity of the CDRR. It accomplished this goal by exploring the associations of the CDRR to psychological outcomes consistent with the attachment literature, namely, problems in the separation-individuation process, unresolved feelings towards caregiver, and current psychological well-being. The results of the PCA revealed a four-factor structure for both CDRR parent versions. The CDRR mother version includes the Disorganization/Punitive, Mutual Hostility, Affective Caregiving, and Appropriate Boundaries scales, while the CDRR father version includes the Disorganization, Affective Caregiving, Appropriate Boundaries, and Punitive scales. Overall, support was provided for the psychometric properties of the CDRR. The CDRR scales demonstrated adequate structural stability, internal consistency, temporal reliability and various forms of validity. Generally, the disorganized and controlling scales were positively related to problematic separation-individuation, unresolved feelings towards caregivers and psychological problems. It is hoped the CDRR will assist researchers in broadening the understanding of psychological outcomes of disorganized and controlling attachment representations in young adulthood.

description: Xylooligosaccharides (XOS) production from sweet sorghum bagasse (SSB) has been barely studied using other edible biomasses. Therefore, we evaluated the XOS content as well as its purity by comparing the content of total sugars from SSB. An environmentally friendly approach involving autohydrolysis was employed, and the reaction temperature and time had variations in order to search for the conditions that would yield high-purity XOS. After autohydrolysis, the remaining solid residues, the glucan-rich fraction, were used as substrates to be enzymatically hydrolyzed for glucose conversion. The highest XOS was observed for total sugars (68.7%) at 190 °C for 5 min among the autohydrolysis conditions. However, we also suggested two alternative conditions, 180 °C for 20 min and 190 °C for 15 min, because the former condition might have the XOS at a low degree of polymerization with a high XOS ratio (67.6%), while the latter condition presented a high glucose to total sugar ratio (91.4%) with a moderate level XOS ratio (64.4%). Although it was challenging to conclude on the autohydrolysis conditions required to obtain the best result of XOS content and purity and glucose yield, this study presented approaches that could maximize the desired product from SSB, and additional processes to reduce these differences in conditions may warrant further research.

description: Flight control programs use PID control modules with user-configurable Proportional (P), Integral (I), and Derivative (D) parameters to manage UAV flying behaviors. Users can adjust these PID parameters during flight. However, flight control programs lack sufficient safety checks on user-provided PID parameters, leading to a severe UAV vulnerability - the input validation bug. This occurs when a user misconfigures PID parameters, causing dangerous states like deviation from the expected path, loss of control, or crash.
 Prior works use random testing like fuzzing, but these are not effective in the three-dimensional search space of PID parameters. The expensive dynamic execution of UAV tests further hinders random testing performance.
 We address PID parameter misconfiguration by combining the Routh-Hurwitz stability criterion with coordinate search, introducing RouthSearch. Instead of ad-hoc identification, RouthSearch principledly determines valid ranges for three-dimensional PID parameters. We first leverage the Routh-Hurwitz Criterion to identify a theoretical PID parameter boundary, then refine it using efficient coordinate search. The determined valid range can filter misconfigured PID parameters from users during flight and help discover logical bugs in flight control programs.
 We evaluated RouthSearch across eight flight modes in PX4 and Ardupilot. Results show RouthSearch determines valid ranges with 92.0% accuracy compared to ground truth. RouthSearch discovers 3,853 PID misconfigurations within 48 hours, while the STOA work PGFuzz discovers only 449 sets, significantly outperforming prior works by 8.58 times. Our method also helped detect three bugs in ArduPilot and PX4.

description: Tissue regeneration in mammals does not occur via the process of dedifferentiation, a process whereby differentiated cells lose their specialized characteristics and revert to a less differentiated state. McGann et al. (2001) showed that mouse C2C12 myotubes treated with newt extract derived from regenerating limbs can re-enter the cell cycle, fragment and proliferate ( a characteristic of muscle dedifferentiation). However, the validity of these studies has been called into question since others have been unable to repeat them. My research attempts to replicate the results of McGann et al, and to carry them further. I examined several strategies for tracking the extract-treated cells and I also repeated the studies in a primary muscle culture system. Furthermore, I examined the effect of the extract on myoblast differentiation. The most effective dedifferentiation assay that I developed involved the microinjection of myotubes with extract and with a GFP plasmid that allowed tracking of the injected cells. Cells were then examined for cell cycle re-entry using BrdU incorporation or Ki-67 immunostaining. In addition, immunocytochemistry and RT-PCR analysis were used to examine the expression or down-regulation of muscle-specific markers. Finally, a preliminary GeneChip analysis was conducted to examine which genes were up or down regulated following extract treatment. The results show that newt extract is able to block the differentiation of confluent myoblasts, resulting in fewer multinucleated, myosin heavy chain expressing myotubes. However, when myoblasts were differentiated into myotubes and subsequently treated with newt extract, the results suggest that cell cycle re-entry and down-regulation of differentiation markers can occur in C2C12 myotubes, but not in primary myotubes. Fragmentation though, was seen in both C2C12 and primary myotubes following treatment or injection with newt extract. Moreover, the fragmented cells appeared to be viable. Transcriptional profiling indicated that newt extract affects genes implicated in cell cycle, transcription, stress, chromatin modification, growth, cell adhesion, extracellular matrix, wound healing and microtubule binding. These findings confirm that mammalian myotubes can be induced to dedifferentiate following treatment with newt extract; however, a differential response was observed between C2C12 and primary muscle cells.

description: A meta-analysis of 14 studies (17 individual effect estimates) on the association between road traffic noise and coronary heart diseases was carried out. A significant pooled estimate of the relative risk of 1.08 (95% confidence interval: 1.04, 1.13) per increase of the weighted day-night noise level L DNof 10 dB (A) was found within the range of approximately 52-77 dB (A) (5 dB-category midpoints). The results gave no statistically significant indication of heterogeneity between the results of individual studies. However, stratified analyses showed that the treatment of gender in the studies, the lowest age of study subjects and the lowest cut-off of noise levels had an impact on the effect estimates of different studies. The result of the meta-analysis complies quantitatively with the result of a recent meta-analysis on the association between road traffic noise and hypertension. Road traffic noise is a significant risk factor for cardiovascular diseases.Quelle: http://www.noiseandhealth.org
The Employee Experience in a Healthy High-Performing Workplace

Subjects: Organizational culture

Healthy organization

description: This study examines management and organizational models, specifically the Healthy Organization and High-Performing Workplace (HPW) models. Because a HPW can also be a Healthy Organization, the models are joined to create the Healthy High-Performing Workplace (HHPW) model. The experience of members within a particular organization, known herein as Company X, is examined. The study addresses the questions: does Company X display HHPW qualities? If Company X does display HHPW qualities, does it always exercise HHPW practices? Finally, what does this mean in terms of the workforce? Organizational culture theory is used to explain how expectations, norms, behaviours, and values are constructed and transmitted, and how organizational structures influence the environment and the employee experience. Data consists of interviews (n=12) and secondary sources. The findings support that Company X displays HHPW characteristics. However, when project deadlines are near or overdue and profit is at risk, certain HHPW practices are ignored.
Emergency Contraception in Post-conflict Somalia: Assessing Awareness and Perceptions of Need

description: Somalia’s reproductive health indices are among the worst in the world. Rates of maternal death, total fertility, and sexual and gender based violence reflect the poor reproductive health outcomes of women living in Somalia. Over two decades of civil unrest left the majority of the population without access to basic health care, particularly reproductive health services. Currently, it is estimated that about 1% of women in Somalia use a modern method of contraception, and the country has yet to register a dedicated progestin-only emergency contraceptive pill. This study seeks to explore levels of awareness and the perceived need for emergency contraception (EC), as well as stakeholders’ knowledge of and experiences with reproductive health services in Somalia. Through interviews and focus group discussions with stakeholders in Somalia, I learned that awareness about vital services like EC is low, while the need for EC and broader reproductive health services is high. Evidently, stakeholders believe awareness, availability, quality care, culture, religion and good governance are important factors for both delivering and accessing reproductive health care. These study findings will fill an important gap in the literature and support efforts to expand and improve reproductive health service delivery in the country.

description: Background: The health effects of sheesha smoking are not well addressed. Objective: To assess the association between sheesha tobacco smoking and gene expression pertinent to cancer. Methodology: Three linked studies were carried out: (1) investigation of gene expression in salivary cells before and after exposure to sheesha tobacco smoke in 15 participants; (2) a systematic review of the association between sheesha and cancer; and (3) a pilot survey to collect data on factors potentially relevant to the uptake and cessation of sheesha tobacco smoking. Results: In the short-term, sheesha smoking significantly reduced the expression of both xenobiotic metabolism genes and other genes known to have altered expression in tobacco related cancers in a range between 1.7 times and 55 times. The systematic review showed that sheesha may increase the risk of lung and esophageal cancers. The pilot survey identified misperceptions about safety, in line with other studies, an approach that could be used to investigate the characteristics of sheesha smokers on a larger scale, and specific issues to probe. Conclusion: High quality epidemiological evidence on long-term effects of sheesha smoking on cancer is lacking. However, sheesha smoking has short-term effects on the expression of genes known to be involved in tobacco-related cancers. This is of major concern given widespread misperceptions about the likely safety of sheesha tobacco smoking.
Flächensparen und Wohnungsnot - ein Widerspruch?

description: Der Flächenverbrauch in Deutschland nimmt seit Jahren ab, jedoch nicht stark genug, um das für 2020 gesetzte 30-Hektar-Ziel zu erreichen. Einer der Treiber des Flächenverbrauchs ist die Wohnbebauung und zwar gerade dort, wo die Bevölkerung eher abnimmt. In Großstädten und Ballungsräumen mit steigenden Bevölkerungszahlen wird dagegen kaum neue Fläche in Anspruch genommen. Die aktuelle Bevölkerungsprognose zeigt trotz Zuwanderung langfristig bundesweit sinkende Bevölkerungszahlen. Bei der Wohnbebauung schwankt die Anzahl der neu gebauten Ein- und Zweifamilienhäuser deutlich weniger als die der Mehrfamilienhäuser. Deren Zahl sank zu Beginn des Jahrtausends stark ab. Dies wirkte sich vor allem auf das Angebot kostengünstiger und Sozialwohnungen aus und führte zu den derzeitigen Problemen auf dem Wohnungsmarkt. Kostengünstige Wohnungen fehlen vor allem in den Ballungsräumen. Mehrgeschossige Häuser, die innerstädtisch auf Brachen, sanierten Altlasten- und Gewerbegrundstücken sowie durch Aufstockungen entstehen, könnten ohne große Auswirkungen auf den Flächenverbrauch Abhilfe schaffen.

description: Land consumption in Germany has been decreasing for years, but not sufficiently to reach the goal to reduce daily land consumption to 30 hectares by 2020. An important driver is housing development, which increases in places, where the population is decreasing. In big cities and urban areas with high settlement pressure land consumption is low even though the population is growing. Current population forecasts show a decreasing population in the long term, which cannot be prevented by migration. The number of oneand two-family houses has remained stable, whereas less multistory buildings have been built since the beginning of the millennial. Concerned are mainly affordable apartments and social housing, as reflected by the current problems on the residential rental market. Affordable apartments are needed in urban areas. Multistory buildings that can be built on fallow wasteland, redeveloped contaminated sites and former commercial properties, do not use additional space. Quelle: https://www.bodenschutzdigital.de
Long-term operating performance: an empirical examination of family and non-family firms listed in Australia
Creators: name: Halili, Enver
Publisher: name: Swinburne
Year: 2024

description: This study conducts a comprehensive investigation on firms listed on the Australian Securities Exchange (ASX) during the period 1998-2010. The research has four major aims. Firstly, the research aims to undertake a comparative analysis of family and non-family businesses by applying ownership structure as an underlying factor and Agency Theory as the conceptual basis. The second aim is to examine the operating performance of family and non-family firms from industry aspects (mining vs non-mining firms). The third aim is to compare and contrast the operating performance of both types of firms for the periods prior and post the Global Financial Crisis (GFC). The last aim is to investigate the impact of value drivers on financial performance of family and non-family businesses. As there is a paucity of studies in the area encompassing Australian family listed firms, this study makes a significant contribution to the literature and to the understanding of family firm performance.
