This dissertation examines ways in which differences in states' political activity laws affect the political attitudes and reported behavior of senior state government employees. Of particular concern is whether a stringent little Hatch Act engenders any "chilling effects" that may lead these workers to shy away from permissible political activities. The study included officials employed in Pennsylvania, which has a restrictive political activity statute, and New Jersey, which has generally permissive laws. Mail questionnaires were sent to 962 officials, 512 from Pennsylvania and 450 from New Jersey. Responses were received from 582 employees, yielding a 61.91% response rate. Compared to New Jersey officials, those from Pennsylvania were less knowledgeable about their state's political activity laws. The Pennsylvania employees also reported being less politically active and less satisfied with their activity, and were more likely to indicate that they would increase their level of political activity if state prohibitions were eliminated. However, compared to their New Jersey counterparts, these officials were no less inclined to engage in permissible political activities. This finding casts doubt on the notion that a highly restrictive statutory climate spawns chilling effects. / Ph. D.

Thesis (M.Sc. (Agric)) --University of Limpopo, 2010 / An experiment was conducted to determine the effect of egg weight on hatchability, hatch-weight and subsequent productivity of Venda chickens. A total of 360 Venda chicken eggs based on their weights were collected within one week and assigned to four treatments with five replicates of 18 eggs per replicate. A randomized design was used. The four treatment weights were below 49 g, between 50 and 59 g, between 60 and 69 g and above 70 g. the eggs were incubated for 21 days. The chicks were raised up to 13 weeks based on their treatments but fed a similar diet. Egg weight was positively and strongly correlated (r2 = 0.727) with hatchability. Similarly, egg weight was positively and strongly correlated (r2 = 0.0.953) with chick hatch-weight. Between one and seven weeks old, Venda chicks hatched from heavier eggs ate less (P< 0.05) than those hatched from lighter eggs. Heavier eggs hatched chicks with better (P< 0.05) feed conversion ratio. However, chicks hatched from heavier eggs tended to have higher (P< 0.05) live weight at seven weeks old than those hatched from lighter eggs. Heavier eggs tended to hatch chicks that had higher (P< 0.05) mortality rates. However, metabolisable energy and nitrogen retention of the chicks aged seven weeks was not (P> 0.05) affected by egg weight. Growth rate and live weight of the chicks aged between one and seven weeks were optimized at different Venda chicken egg weights of 56 (r2 = 0.514) and 60 (r2 = 0.870) g, respectively. Egg weight had no (P> 0.05) effect on metabolisable energy, feed conversion ratio, growth rate, live weight, carcass weight and carcass parts of Venda chickens aged between eight and 13 weeks except fat pad weight. Venda chickens hatched from lighter eggs had lower (P< 0.05) fat pad weights than those hatched from heavier eggs. Meat samples of chickens hatched from lighter eggs had higher (P< 0.05) nitrogen contents. It is concluded that Venda chicken egg weight affects (P< 0.05) egg hatchability, chick hatch-weight, growth rate, live weight and carcass characteristics of the chicken. However, these variables are optimized at different egg weights. This has implications on selecting eggs for incubation.

Canada’s Patented Medicines (Notice Of Compliance) Regulations fail to achieve the intended purpose of balancing innovation with timely generic market entry. An examination of the inefficiencies created by the Canadian regulations reveals that key features of U.S. pharmaceutical law should be adopted to improve the disjointed regulatory system that impedes generic competition. Specifically, the regulations should be amended to consolidate multiple proceedings into one cause of action that evaluates patent validity. An economic incentive to challenge weak patents should also be introduced in Canada. These features encourage competition without deterring pharmaceutical research and development because only patents that are not truly inventive will be invalidated after a full inquiry. As such, the intellectual property laws will continue to satisfy Canada’s international intellectual property obligations and protect innovative medicines and allow recovery of costs and monopoly profits to new and useful pharmaceutical products.

Currently, most Americans are 2 to 4 generations removed from the farm, as only 2% are involved with agriculture. Thus, verifying the importance of agriculture education implementation to promote the agriculture industry. MSU has a novel Hatch-out Program in attempt to bridge the gap in agriculture awareness. Research for this thesis first evaluates previous participants of the Hatch-out Program to assess satisfaction to determine if modifications are needed. This thesis will conclude with the implementation and validation of the modified curriculum, lesson plans, as well as activities and materials into the classroom. A post-implementation survey was also given to the teachers to evaluate ease of implementation as well as age-appropriateness. Results revealed an increase of knowledge across all grades in respect to the pre- and post-test. Survey results revealed an ease of implementation as well as age-appropriateness from teacher surveys.

The study that I detail in the following thesis is a component of a three-part collaborative project to provide the U. S. National Park Service and Cape Cod National Seashore (CCNS) with data needed to inform management decisions for protection of the endangered northwest Atlantic Roseate Tern (ROST) during fall pre-migratory staging. This study was designed to address objectives related to hatch-year (HY) ROST behavior and survival in response to human and non-human activities and environmental variables at CCNS. Behavioral data showed that disturbance, specifically human and non-human activities, were related to increased HY ROST locomotion (flying and walking). We also found that environmental variables, including day of season and time of day were related to increased locomotion. Flock-level HY ROST begging behavior was decreased in the presence of human disturbance, but we did not see the same effect at the individual level. We found no evidence that the observed behavioral effect of disturbance resulted in decreased residency, recruitment, or staging duration of HY ROST at CCNS. Our work demonstrates that disturbance events around staging flocks have behavioral consequences, but it is unknown whether HY ROST behavioral responses to disturbances are great enough to impact survival after departure from CCNS. A conservative and proactive management strategy to minimize the potential for negative carryover effects on survival should limit ROST exposure to disturbance, particularly human activities, by exclosing staging sites between mid-July–mid-September to encompass the period of time when the highest number of ROST use CCNS. / Master of Science / The study that I detail in the following thesis is one component of a three-part collaborative project to inform management decisions for protection and recovery of the endangered northwest Atlantic Roseate Tern (ROST) population while they prepare for southward migration at Cape Cod National Seashore, MA (CCNS). This study was designed to address objectives related to hatch-year (i.e., HY, birds that were just hatched on the breeding grounds and now flying south for the first time) ROST behavior and survival in response to human and non-human activities and environmental variables at CCNS. We found that disturbance, specifically human and nonhuman activities were associated with increased locomotion (walking and flying). We also found that certain environmental variables, including day of season and time of day were related to increased locomotion rates. Additionally, proportions of HY ROST within a flock that engaged in begging behavior decreased in the presence of human disturbance, but we did not see the same effect at the individual level. We found no evidence that the observed behavioral effect of disturbance resulted in decreased residency, or time spent at CCNS by HY ROST. Our work demonstrated that human activity around tern flocks had behavioral consequences, but it is unknown whether HY ROST behavioral response to human disturbances was great enough to impact survival after departure from CCNS staging grounds. A risk-averse management strategy would entail limiting ROST exposure to potential human disturbance by closing off staging sites between mid-July–mid-September to human activity to encompass the period of time when the highest number of ROST use CCNS.

Thesis (MSc. Agriculture (Animal Production)) -- University of Limpopo, 2015 / Three experiments were conducted to determine the effect of in ovo glucose injection on egg hatchability, chick hatch-weight, productivity and carcass characteristics of indigenous Potchefstroom koekoek chickens. A complete randomized design was used in all the three parts of the study (from incubation, 1-49 days old unsexed chickens and 50-91 days old female chickens). On day 18 of incubation the developing eggs were subjected to the following treatments: 0- (no glucose or water injected), 0+ (only water injected), 5, 10, 15 or 20 mg of glucose per egg. Each treatment had three replications and there were 20 eggs per replicate. A quadratic model was used to determine in ovo glucose injection levels for optimal egg hatchability, chick hatch-weight and chick to egg weight ratio of Potchefstroom koekoek chickens. In ovo glucose injection improved (P<0.05) egg hatchability, chick hatch-weight and chick to egg weight ratio of the chickens. Egg hatchability, chick hatch-weight and chick to egg weight ratio Potchefstroom koekoek chickens were optimized at different injection levels of 4.50, 10.43 and 12.00 mg of glucose per egg, respectively. Unsexed day-old chicks from the first experiment (according to their initial treatments and replicates) were used in a complete randomized design having six treatments, replicated three times, and having ten birds per replicate. Glucose injection levels increased (P<0.05) feed intake, growth rate, feed conversion ratio, live weight, metabolisable energy and nitrogen retention of female Potchefstroom koekoek chickens aged 1 to 49 days. However, growth rate, live weight, metabolisable energy intake and nitrogen retention of the chickens were optimized at glucose injection levels of 3.92, 4.36, 10.67 and 13.50 mg per egg, respectively. Female chickens from the second part of the study (according to their initial treatments and replicates) were used in a complete randomized design having six treatments, replicated three times, and having five birds per replicate. In ovo glucose injection levels improved (P<0.05) on feed intake, growth rate, feed conversion ratio, live weight, metabolisable energy and nitrogen retention of female Potchefstroom koekoek chickens aged 50 to 91 days. However, only feed conversion ratio and metabolisable energy intake of the chickens were optimized at glucose injection levels of 12.15 and 5.57 mg per egg, respectively. Injection level also improved (P<0.05) carcass, breast, v drumstick, thigh, wing, gizzard and liver weights of female Potchefstroom koekoek chickens aged 13 weeks. In ovo glucose injection increased (P<0.05) breast meat tenderness, juiciness and flavour of female Potchefstroom koekoek chickens aged 91 days. However, breast tenderness, juiciness and flavour of female Potchefstroom koekoek chickens were optimized injection levels of 13.50, 19.25 and 10.83 mg of glucose per egg, respectively. No chicken deaths were observe

Field and laboratory experiments were conducted to elucidate various factors influencing the temperature-dependent larval eclosion of winter moth, Operophtera brumata L, in New England. We found no difference in duration of the embryonic stage of eggs reared from larvae collected in Massachusetts (MA) and on Vancouver Island, British Columbia (BC), where winter temperatures are rarely below freezing. The number of growing degree days (GDD) required for larval eclosion declined with the number of days chilled in the laboratory and number of days below freezing in the field, confirming the findings of previous studies. Thus, eggs hatched with fewer GDD, when the spring came later than usual. Date of oviposition had no effect on date of hatch. Eggs laid by naturally occurring (feral) females hatched sooner with lower GDD than eggs from laboratory-reared females from MA and BC held on the same trees over the winter. South-facing eggs on the stems of trees hatched on average 1.6 days sooner than north-facing eggs. Growing degree days calculated from bi-hourly measures of temperature were 15% greater than GDD estimates based on the average of daily maximum and minimum temperatures, as used by many GDD estimates made for online sources. Over two years, the mean GDD in ⁰C for hatch of feral eggs based on bihourly temperature measurements, a 1 Jan start date and a 3.9⁰C developmental threshold was 176.53 ± 6.35SE

In a family house not far from Brno, there is an entryway hole for getting into the space under the floor. The hole is covered by a high weight concrete hatch. For easier manipulation with the hatch an opening mechanism was designed and manufactured. This mechanism had been installed under the hatch and nowadays it works well. This master’s thesis deals with description of main components of the mechanism and their function. Load analysis and stress-strain analysis are the major part of this thesis. At the end of this work the analysis results are commented and some suggestions for further research are proposed.
