Effects of Alternative Silvicultural Treatments on Regeneration in the Southern Appalachians

Atwood, Chad Judson 11 June 2008 (has links)
Harvesting practices in the southern Appalachians have moved away from clearcutting in favor of variable retention harvesting systems. A study was initiated in 1995-8 to investigate the effects of retaining varying numbers of residual trees on regeneration in seven silvicultural treatments. A second study specifically focused on stump sprouting in only three of those treatments. The treatments for first study included: a clearcut, commercial harvest, leave-tree, shelterwood, group selection, midstory treatment, and an uncut control. The second only focused on the clearcut, leave-tree, and shelterwood. These treatments were implemented in seven stands in Virginia and West Virginia over two physiographic provinces, the Appalachian plateau and Ridge and Valley. The stands were even-aged oak dominated Appalachian hardwood stands on fair quality sites with average ages ranging from 63 to 100 yrs. Permanent plots were randomly located in each stand and all overstory trees (>5m tall) were inventoried and tagged prior to harvest. Regeneration was also quantified. Harvest occurred between 1995-8. For the current studies the plots were re-inventoried 9-11 years post-harvest and all regeneration in all treatments as well as stump sprouts in the selected treatments were quantified. The first study utilized a mixed model ANOVA to analyze five species groups: oak, maple, black cherry-yellow-poplar, miscellaneous, and midstory. Response variables included importance value, average height, and density compared within species group and among treatments. Differences between sprout and seedling origin regeneration were also investigated within species group among treatment. Results indicated that oak densities were similar in all of the treatments, and stump sprouts were larger and more frequent than seedlings. Maple exhibited an increase from pre-harvest overstory importance and exhibited competitive sprouting. The black cherry-yellow-poplar group had few but highly competitive sprouts and a considerable increase in seedling origin regeneration in all treatments. The miscellaneous species densities increased as well with more competitive sprouting in some treatments. The midstory species were excluded from the analysis as it was assumed these species would not occupy canopy positions in a mature stand. The second study investigated differences in the percent of stumps that sprouted and the number of sprouts per stump. The percent data were analyzed using a non-parametric one-way ANOVA and regression analysis, while the sprouts per stump data were compared in a mixed model ANOVA and regression. Species were combined into six groups: the red oak group, chestnut oak, red maple, white oak/hickory group, mixed mesic group, and midstory group. The plateau tended to have reduced sprouting compared to the Ridge and Valley for most species groups and treatments. The red oak group, chestnut oak, and red maple exhibited reduced sprouting with increased residual basal area. The mixed mesic group did not show any effect in sprouting related to residual basal area. Only chestnut oak showed fewer sprouts per stump as residual basal area increased. / Master of Science

Har jag inte gjort min markservice än? : En kvalitativ studie om socionomers erfarenheter av en sjukskrivning / Have I not done my groundservice yet? : A qualitative study of social workers experiences of being on sick leave

Kohler, Andrea, Tillman Blomberg, Kajsa January 2024 (has links)
Stressrelaterad psykisk ohälsa har blivit en allt vanligare orsak till sjukskrivningar, särskilt inom människovårdande yrken som socialt arbete. Denna kandidatuppsats undersöker socionomers erfarenhet av en stressrelaterad sjukskrivning Genom kvalitativa intervjuer med sju socionomer som varit sjukskrivna för stress, fångas deras personliga berättelser och erfarenheter med fokus på stresshantering och lärdomar från sjukskrivningen. Studien visar att både individuella egenskaper och arbetsmiljö spelar en stor roll i hur stress hanteras och upplevs. En gemensam upplevelse var att de behövde lära sig nya sätt att hantera stress och sänka sina egna krav för att uppnå en mer hållbar yrkesroll. / Stress-related health issues have become increasingly common, especially in caregiving professions such as social work. This Bachelor´s thesis examines social workers experiences of stress-related sick leave. Through qualitative interviews with seven social workers, who have been on sick leave due to stress, their personal stories and experiences have been captured with a focus on Stress Management and learning from a sick leave. The study shows that both individual characteristics and work environment play a significant role in how stress is managed and perceived. A common experience was the need to learn new ways to cope with stress and set lower personal expectations.

The impacts of seven silvicultural alternatives on vascular plant community composition, structure, and diversity in the southern Appalachians

Wender, Bryan William 10 November 2000 (has links)
The effects of seven silvicultural prescriptions were examined one full growing season post-treatment on five sites in the Ridge and Valley, Cumberland Plateau, and Allegheny Plateau of Virginia and West Virginia. Prescriptions were (1) control, (2) understory control with herbicide, (3) group selection, (4) high-leave shelterwood, (5) low-leave shelterwood, (6) leave tree, and (7) clearcut. The effects of each treatment on the vascular plant community were characterized by changes in species diversity, species composition, exotic species richness, Raunkiaer's life-forms, and growth-forms. Pre-treatment, baseline data, and a randomized block design ensured the precision of post-treatment comparisons. High-disturbance treatments (i.e., low-leave shelterwood, leave tree, clearcut) exhibited lower tree-stratum species richness than unharvested treatments. Prescriptions had no effect on shrub-stratum richness. Compared to the control, woody, herb-stratum richness was higher in harvested treatments. Non-woody herb-stratum richness was unaffected. No differences in herb-stratum species diversity were detected using Shannon's (exp H') or Simpson's (1/D) indices. Non-woody species richness per 2-ha treatment plot was significantly higher than the control for high-disturbance treatments. Pre- vs. post-treatment species composition was least similar for high-disturbance treatments, as measured by qualitative and quantitative community similarity indices. Exotic woody species richness was unaffected by treatment; however, non-woody exotic species were more prevalent in high-disturbance treatments. Hemicrytophytes replaced phanerophytes as the most important life-form for harvested treatments. Therophytes were more important in harvested treatments, while the proportion of cryptophtes and chamaephytes did not change in response to treatments. Tree and shrub growth-forms were less dominant in harvested treatments, while graminoids and annual/biennial forbs were more important for high-disturbance treatments. These data represent only the initial results of a long-term study designed to examine plant-community response to silviculture for one harvest rotation length. Long-term results will aid in devising management strategies that address concerns for biodiversity without devaluing traditional resource demands. / Master of Science

Clergywomen and Role Management: A Study of PC(USA) Clergywomen Negotiating Maternity Leave

Sharp, Erin Colleen 08 June 2012 (has links)
While there is abundant research and literature on the transition to becoming a mother while working and on mothers and work-life balance, literature on clergy and, in particular, clergywomen and work-life balance is scarce. This study contributes to that literature by utilizing role theory and grounded theory methods to investigate the experience of 12 clergywomen who negotiated maternity leave with their congregations and the implications of that process on how they understood and managed their roles as mothers and pastors. The result is a model for role management through the process of negotiating maternity leave which identifies and describes the causal conditions; personal, church and intervening factors; overall experience of negotiation and consequences of the negotiation, including decisions about role management. Major findings include the observations that the most influential church factor seems to be the overall stability and organizational health of the congregation and its leadership and that a presbytery level policy may be the only effective intervention in a difficult negotiation. Limitations of the study, as well as recommendations for future study, clinical implications, and recommendations for denominational leaders are also discussed. / Master of Science

Three Essays on Econometric Modeling and Application: Health and Consumer Behaviors

Kim, Namhoon 18 April 2018 (has links)
In the three chapters of my dissertation, I analyze the individual behaviors including health (vaccination and preventive care) and consumer (financial literacy) behaviors and the corresponding interventions by nonlinear econometric modeling. In the first chapter, I suggest an appropriate econometric model that investigates the effect of paid sick leave on workers' decision to receive the seasonal flu vaccination. For this investigation, I apply a Bayesian non-linear structural regression model with one-outcome and two-endogenous equations. The results of my estimation indicate that having paid sick leave affects workers' vaccination decisions differently based on their income levels. Low-income workers are willing to be vaccinated because they perceive the high cost of claiming paid sick leave. However, high-income workers are willing to be vaccinated because paid sick leave reduces the cost of vaccination for seasonal flu. In the second chapter, I suggest new econometric regression models that investigate the effect of "Don't Know" or "Refuse" (DK/RF) responses on parameter identification. I estimate the effect of group characteristics and financial education on the level of young respondents' objective financial knowledge and find the actual effects and biases by my suggested models. This study examines six questions about personal finance and selects covariates in the 2015 National Financial Capability Study (NFCS). Because these questions include DK/RF responses, a simple regression model that does not consider DK/RF responses could lead to misleading conclusions, such as gender/income difference and educational effectiveness in schools. In the last chapter, I investigate the effect of three health-related interventions including a doctor's recommendation, information about human papillomavirus (HPV), and HPV vaccination, on the misuse of cervical cancer screening including too-early screening, unnecessary HPV test, annual Pap test, and no Pap smear that are not recommended for women younger than 30 years. I examine the National Health Interview Survey conducted in 2015 and applies binary and multinomial logistic regression models. From the estimation result, I observe that doctor's recommendation plays a significant role in increasing the probability of receiving cervical cancer screening while it induces the too-early screening, unnecessary HPV testing, and overuse of Pap smears. / Ph.

From this investigation, I observe the disadvantage of rejecting financial education offers in obtaining proper financial knowledge and the ineffectiveness of formal and informal financial education on the level of objective financial knowledge. In addition, I observe few or no gender, income, and age differences in the level of objective financial knowledge among young adults. In the last chapter, I investigate the effect of a doctor's recommendation, information about human papillomavirus (HPV), and HPV vaccination on the too-early screening, unnecessary HPV test, annual Pap test, and no Pap smear that are not recommended for women younger than 30 years.

Komparace české a slovenské právní úpravy dovolené / Comparison of Czech and Slovak legal regulation of leave

Blatný, Richard January 2021 (has links)
1 Abstract and keywords in the English language Comparison of Czech and Slovak legal regulation of leave Abstract The dissertation contains an overview of labor law legislation, especially the regulation of holidays, in the territory of historical Bohemia, Moravia and Silesia on the one hand and in the territory of today's Slovakia on the other hand. For a better understanding of the issue, an overview of the development of working conditions and labor protection in a given time context in both cultural areas is also provided. I believe that the presented comparison of legal regulations in both territories is an interesting excursion not only in terms of labor law itself, but also in the field of legal history. I believe that in the presented summary of the work it provides important and interesting expanding knowledge in the field of labor law and social security law. In my opinion, similar work was lacking in our market, and therefore it can be assumed that in this direction it will contribute to its enrichment if it is possible to realize its book edition, which is under negotiation. An overview of the material described above is given in twelve chapters since the beginning of the 14th century, when labor relations developed in the Czech lands, about which written reports already exist. In the case of...

Návrat žen po rodičovské dovolené do zaměstnání / The return to work of women after parental leave

Růžičková, Lucie January 2015 (has links)
SUMARRY The focus of this dissertation is the return to work of women after parental leave. The paper explores the topic of maternity and parental leave and care required by pre-school children. It further looks at the current employment status of these women on the job market, along with the offer of flexible forms of employment. The current situation in the Czech Republic is compared to other countries, mainly member states of the European Union. An empirical study based on a questionnaire survey is also a part of this paper. This survey examines the situation of a number of female employees of VZP ČR on parental leave as well as their managers and employees after return to work from parental leave. Based on the results of the survey, this paper proposes a programme, which should help female employees of VZP ČR with a smoother transition while returning to work.

Sladění rodinného a profesního života / Reconciliation of work and family life

Vondrášková, Iveta January 2018 (has links)
Reconciliation of work and family life Abstract This thesis deals with the reconciliation of work and family life in the Czech Republic from a legal perspective. Finding a suitable balance between work and family life enables an individual to return to work sooner from maternity and parental leave. This balance also has a positive effect on the productivity of employees, birth rates, elimination of gender stereotypes and causes a reduction of the unemployment rate among women. The purpose of this paper is to provide a comprehensive overview of the number of articles of employment law and social security law that are relevant to the issues of reconciliation of work and family life, to analyze the relevant legislation, and to draw attention to some practical problems. Also, the paper will evaluate the impact of this legislative framework and legal institutes on work and family life and recommend alterations "de lege ferenda". The thesis of this paper is that reconciliation of work and family life is an endless process and that there are several problem areas related to it that need improvement within the Czech Republic. The work is divided into three chapters. The first chapter identifies the main issues related to the reconciliation of work and family life. It gives the overview of the international,...

No. of bitstreams: 1 deniseberetta_dissert.pdf: 1517104 bytes, checksum: babf62d67de911fbbe1915e031c6d8fa (MD5) Previous issue date: 2001-12-21 / The nursing working conditions in hospitals have been considered insalubrious since these workers are liable to many risks including physical, chemical, biological, ergonomic, mechanical and psychosocial. As a result of this exposure, they may become ill; consequently staying off work. This is an epidemiological study with a census to describe the working absences due to sick leave of nurses from a general teaching hospital. These absences were registered at the Centro de Atendimento ao Trabalhador (CEAT) in the period from 1995 to 1999. A total of 1,002 registrations of absences from working of members of nursing team was analyzed: 9.1% nurses, 1.7% nursing technicians, 69.7% nursing assistances and 19.5% of nursing orderlies. These people were related to 1,986 episodes of sick leave during the studied period: 1,826 (91.4%) by health licenses; 123 (6.2%) by working accidents; and 37 (1.2%) by maternity leave. According to the analysis of characteristics related to these absentees, the majority was women and workers aged between 31 to 40 years old, married, with full-time work of 1 to 6 years; in general, the period of time spent away from work was 1 to 4 days, and mostly employees were working in complex units. The characteristics of the episodes of absenteeism by health licence were frequently due to genito-urinary problems, badly defined diseases and respiratory system diseases. The nursing assistants and the nursing orderlies had registration of all classifications of the International Statistical Classification of Disease and Related Health Problems (1994). This study showed some ethic-legal infractions mainly in relation to the nursing orderlies as well as showing several factors which may be related to the episodes of working absences. Therefore, it may give ways to better analysis of this situation in the hospital improving the current working conditions; moreover, a further deeper investigation of absenteeism which causing more serious and longer problems. / As condições de trabalho da enfermagem em hospitais tem sido consideradas insalubres pela exposição a riscos de natureza física, química, biológicas, ergonômicas, mecânicas e psicossocial, provocando adoecimento e consequentemente afastamentos do trabalho. Nesta abordagem realiza-se este estudo epidemiológico, censitário que teve como objetivo descrever os afastamentos do trabalho por motivo de licença médica de exercentes de enfermagem de um hospital geral de ensino, registrados no centro do atendimento do trabalhador (ceat), no período de 1995 à 1999. Foram analisados os registros de afastamentos do trabalho de 1002 pessoas da equipe de enfermagem, sendo 9,1% de enfermeiros, 1,7% de técnicos de enfermagem, 69,7% de auxiliares de enfermagem e 19,5% de atendentes de enfermagem, que envolvem-se em 1986 episódios de afastamentos no período em estudo, sendo 1826 (91,4%) por licença saúde; 123 (6,2%) por acidentes de trabalho e 37 (1,2%) por licença gestante. Nota de Resumo Na análise das características dos episódios de afastamentos constatou-se que acometeu principalmente mulheres, funcionários com idade entre 31 e 40 anos, na categoria de casados, com tempo de serviço de 1 a 6 anos, tempo de afastamento de 1 a 4 dias e entre aqueles que atuavam em unidades complexas. Nota de Resumo Quanto às características dos episódios de afastamento por licença saúde, ficam ressaltados que os problemas de saúde mais freqüentes foram do sistema geniturinário, doenças mal definidas e doenças do sistema respiratório e que os auxiliares de enfermagem e atendentes de enfermagem tiveram registros em todas as classificações de doenças do classificação internacional de doenças (cid) - 10. Assim, com este trabalho identificou-se infrações ético legais, principalmente em relação ao atendente de enfermagem e que vários fatores podem ser relacionados com os episódios de afastamento do trabalho, dando subsídios para uma melhor análise desta situação neste hospital, para melhoria das condições de trabalho vigente, além de sugerir um investigação mais profunda sobre os afastamentos que estão provocando problemas mais sérios e com maior duração.

List of tasks was established in order to achieve the purpose of the master work, i.e. analysis of the essence of expatriates’ management, identification of the factors that influence expatriate job satisfaction, identification of the factors that influence propensity to leave the company, empirical test of the influence of expatriate job satisfaction on propensity to leave the company. Literature about expatriates, job satisfaction and propensity to leave the company was analysed in the first part of the work. Afterwards, elements that have influence on expatriate job satisfaction were selected. Finally, theoretical model based on the literature analysis results was created. Empirical test was executed in order to test proposed expatriate turnover management model. Final list of elements that have influence on expatriate job satisfaction was created as a result of qualitive research. Later on quantitive research was executed during which means of model elements and relations between them were evaluated. Research partly approved the theoretical model and showed that there was relation between expatriate job satisfaction and propensity to leave the company. Conclusions and practical interpretation for managers was proposed at the end.
