Low autonomic arousal, as measured through resting heart rate, has been shown to be one of the best-replicated biological correlates of antisocial and aggressive behaviour. According to the stimulation seeking theory, low arousal represents an unpleasant physiological state. In line with this theory, antisocial individuals purposely engage in antisocial and aggressive acts in an attempt to increase stimulation and achieve more agreeable arousal levels. If, as the stimulation seeking theory suggests, the function of antisocial behaviour is to increase physiological arousal levels, exposing antisocial individuals to functionally equivalent forms of arousing situations (e.g., aerobic exercise) should result in a reduction in aberrant conduct. Although a growing body of literature indicates that antecedent exercise is effective at reducing antisocial and aggressive behaviours, the present investigation sets out to explore two fundamental questions about this approach that remain unclear. First, there is a paucity of research examining the temporal effects of antecedent exercise. Secondly, little is known about the mechanism of action accounting for behavioural improvements following exercise. The present investigation involved 4 students (age range 11-14) enrolled in a closed behavioural classroom due to severe aggressive, disruptive, and oppositional behaviours. Through the use of an alternating treatment design with baseline, students were first exposed to baseline conditions and then to two experimental conditions, (i.e., an antecedent exercise condition and a control condition) in a randomized fashion. Results indicated that 30 minutes of moderate to intense aerobic exercise resulted in approximately 90 minutes of behavioural improvements. In addition, results suggest an inverse relationship between arousal levels and behavioural difficulties. The potential utility of antecedent exercise as a treatment alternative in schools for students with severe antisocial behaviours is discussed.

Parte-se de uma perspectiva normativa dos institutos. Analisa-se se há e, em caso positivo, sob quais condições, compatibilização de aludida estabilização com as prerrogativas materiais e processuais conferidas ao Poder Público. O trabalho é dividido em duas partes: na primeira, são expostas as características principais que cercam o instituto da estabilização; na segunda parte, estuda-se a estabilização com o enfoque específico na Fazenda Pública. São apresentadas três hipóteses como eventuais óbices à estabilização: (i) o princípio da indisponibilidade do interesse público; (ii) o reconhecimento doutrinário de um regime jurídico único formado entre a estabilização e a ação monitória (microssistema), daí decorrendo a incidência da remessa necessária também como condição para estabilização, muito embora esteja legalmente prevista, de forma específica, apenas para a ação monitória (art. 701, § 4º, CPC/15); e (iii) a exigência legal da remessa necessária como condição para a estabilização, tendo-se em conta apenas a sua regra geral (art. 496, CPC/15), independentemente de qualquer consideração acerca da norma específica contida no art. 701, § 4º, CPC/15. Conclui-se, após afastar as três referidas hipóteses, pela possibilidade de estabilização da tutela antecipada antecedente contra a Fazenda Pública. Por fim, em capítulo próprio, investiga-se acerca do cabimento da estabilização no âmbito dos Juizados Especiais, concluindo-se, no particular, pela sua impossibilidade, dadas as peculiaridades do procedimento sumaríssimo. Palavras-chave: Estabilização. Fazenda Pública. Tutela antecipada antecedente. Compatibilização. Remessa necessária.

The Mississippi Sound is underlain by late Pleistocene aged sediments of the Biloxi, Prairie, and Gulfport Formations topped by an erosional unconformity, which was an exposed land surface during the sea level low-stand of the last glacial maximum. During that period, rivers and streams draining upland watersheds cut across the exposed coastal plain incising a network of distributary fluvial channels. Subsequent sea level rise covered the incised drainage network with a relatively thin (10-20 m) layer of reworked Holocene aged sediments. Here, an extensive database of archived and newly collected seismic reflection profile data, as well as archived core data, is analyzed to map the paleotopography and the paleo-drainage network of the Pleistocene-Holocene unconformity surface beneath the western Mississippi Sound. Approximately 255 km of seismic data was acquired with a 2-16 kHz chirp sub-bottom profiling sonar. Additionally, 978 km of seismic data was accessed through a United States Geological Survey archive along with over 20 historical cores. Results indicate that the Pleistocene-Holocene unconformity under the western Mississippi Sound is gently dipping to the southeast (<0.05°) and contains a complex network of incised paleofluvial channels with relief ranging from 5-10 m and widths ranging from 0.3–2 km. A conceptual model for paleo-channel incision and infilling as well as modern analogue depositional environments are presented.

abstract: 摘要 在复杂多变的商业环境中，企业传统的人力资源管理已经难以应对日益频发的员工职业倦怠、人际间矛盾冲突、频繁跳槽等局面与问题。企业员工工作的价值与意义早已不再是传统的雇佣模式下，通过出卖劳动力或智力从而获得工资以实现“养家糊口”的目的那么单纯与简单，员工也希望通过辛勤的工作，以获得个体的幸福感、荣誉感与认同感等。对于现代企业的管理者而言，员工追求事业的提升、个人价值的实现，不仅体现在薪酬、福利待遇的提升，更重要的是员工个人的成长以及潜能和竞争力的提升。 随着组织行为学和心理学的不断发展与演变，与员工幸福感相关的研究备受关注。对现代企业而言，管理者借助制度设计对员工幸福积极管理，可以最大限度地发挥员工的积极性、主动性与创造性，实现员工与企业之间的利益相趋同，从而更为高效地实现组织的目标。基于此，本文以民营企业员工工作幸福感作为研究的切入点，借助理论分析、问卷调查和实证分析相结合的研究方法，系统深入地研究我国民营企业员工工作幸福感的构成、可控前因和绩效后果等问题。 本文研究发现： 第一，员工薪酬的提高有助于员工工作幸福感的提升，薪资对基层员工幸福感的影响显著高于其对高层员工幸福感的影响； 第二，完善的晋升机制对于中层员工而言更能提升其幸福感，完善的晋升机制更有利于中层员工； 第三，公平性的提高有助于提高员工工作幸福感，而且这种正效应更多体现在基层员工群体之中； 第四，高层员工更注重自我价值的实现，高层员工的工作挑战性越高，其自我实现需求获得的满足感则约高，但是对于基层员工和中层员工而言，其效果则恰恰相反，基础员工和高层员工更多地将工作挑战性和压力看作是一种负面的因素； 第五，员工幸福感的确会给企业带来正向的绩效。 本文的研究框架和实证结论不仅可以丰富学术界有关员工工作幸福感的研究，而且为企业管理者进行绩效管理以及员工工作质量的提升提供理论和实证借鉴。 / Dissertation/Thesis / Doctoral Dissertation Business Administration 2019

Matagorda Peninsula is located along an interfluvial region of the central Texas coast in the northwestern Gulf of Mexico. The Pleistocene Beaumont Clay underlies the coastal plain and inner continental shelf and controls the general slope of the coast in this region. This clay surface also creates low accommodation space for the preservation of modern sediments. As a result, only a thin (1 m) layer of transgressive Holocene muddy sand extends throughout the lower shoreface. On 15 July, 2003, Hurricane Claudette (Category 1) made landfall on the peninsula. Following the storm, the shoreface was found to be an extensively eroded surface. Most obvious on this surface was an area containing numerous scour pits on the lower shoreface. These pits extended through the Holocene sediment and into the underlying Beaumont Clay. By the following July, the shoreface exhibited a relatively flat and featureless appearance. Rapid infilling of the pits was attributed to the high sediment supply to the area from converging longshore currents and by the relatively high accommodation space offered by the scoured areas. A large amount of sediment was removed from the lower shoreface where the formation of scour pits occurred. This sediment would have been available for depositionin storm layers both inshore and offshore of the scoured area. Within scour pits, accommodation space was high, resulting in sediment deposition and rapid infilling of the pits. Outside of the scour pits, accommodation space remained low and sediment deposition did not occur. Preservation potential of the sediment record on the shoreface was low and was controlled by cycles of erosion and deposition during storm events. Antecedent geology of the shoreface and the sedimentary processes occurring during and after the storm supported arguments against the assumptions used by the classic "profile of equilibrium" model. Finally, the heavily scoured surface represents a geohazard to development of nearshore regions.

The industrialised world of today is characterised by transformation and concepts such as downsising, rightsising and restructuring have become a reality. South Africa is not excluded from this worldwide phenomenon. Economic and political changes as well as the shrinking labour market are also aggravating circumstances, which lead to increased job insecurity. This phenomenon might have a negative impact on employees' work engagement Due to all these changes, most organisations have to survive in a competitive global economy. Their survival depends on their ability to satisfy customer needs, while achieving quality, flexibility, innovation and organisational responsibility by the engagement and commitment of employees. The objective of this study was to investigate the relationships between antecedents (work role fit, co-worker relations, supervisor relations, co-worker norms, self-consciousness, resources and growth), psychological conditions (i.e. psychological meaningfuhaess, psychological availability, and psychological safety) and work engagement in a financial institution. A cross-sectional survey design was utilised. Employees (N= 132) in a financial institution, more specifically the branch-banking unit of FirstRand Group in the Free State Province, were included in the study. The Work Experience Scale and the Work Engagement Scale were administered together with a biographical questionnaire. Descriptive and inferential statistics were used to analyse the data. The results showed that psychological meaningfuhaess and psychological availability were significant predictors of work engagement. Cognitive, emotional and physical resources had the strongest effect on work engagement. Multiple regression analyses showed that psychological meaningfuhaess partially mediated the relationship between work role fit, co-worker relations, growth and work engagement. A total of 5% of the variance in psychological meaningfulness and a total of 2% of the variance in psychological availability were predicted by work role fit. Psychological availability partially mediated the relationship between resources, self-consciousness and work engagement. Recommendations for future research were made. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2009.

The CDC estimated that rates of children’s physical activity are extremely low which could lead to various health problems (e.g., hypertension, lipid disorders). Fortunately, previous research has demonstrated that peers, specifically peers identified as preferred, might influence children’s levels of physical activity. However, this variable has not been experimentally manipulated. The purpose of the current study was to assess the effects of peer presence on the MVPA exhibited by kindergarten children, by exposing participants to peers identified as preferred. Results indicated that the presence of a peer identified as preferred increased the levels of MVPA for one participant but failed to increase three participants’ levels of MVPA. Additionally, two participants’ MVPA moderately increased during the first antecedent manipulation but failed to maintain in the second phase of the antecedent condition. In regards to engagement with peers, participants engaged in higher levels of interactive play with peers than parallel play.
