Coach Mid-Season Replacement and Team Performance in Professional SoccerThe coaching carousel or turnover is an extreme but frequently occurring phenomenon in soccer. Among the reasons for firing a coach, the most common is the existence of a shock-effect: a new coach would be able to motivate the players better and therefore to improve results. Using data from the Spanish Soccer League during the seasons from 1997-1998 to 2006-2007, this paper investigates the relationship between team performance and coach change over time. The empirical analysis shows that the shock effect of a turnover has a positive impact on team performance in the short term. Results reveal no impact of coach turnover in the long term. The favourable short-term impact on team performance of a coach turnover is followed by continued gradual worsening of results. The turnover effect is non-existent when the comparison between the new coach and the old coach is done over 10, 15 or 20 matches before and after termination.

While the relation between terrorism and tourism has been an important topic for tourism research, the questions whether terrorism affects tourism immediately and how long after a terrorism event tourism recovers are, as yet, not clearly answered. The aim of this article is to better understand the magnitude and temporal scale of the impact of terrorism on tourism. To this end, a research model differentiating between short-term and long-term effects of terrorism on tourism is developed and analyzed for the destination Israel using data on tourists from Germany. The results show both short-term and long-term impacts with a time lag between the terrorist event and the beginning of tourism decline of 1 or up to 6 months. An economic influence on the development of tourist arrivals was not detected, but seasonality plays an important role in the relationship between terrorism and tourism.

A case study was conducted in order to track the human brain adapts to changing demands by physical exercise. Reaction time and amplitude discrimination capacity of the individual were measured with the Brain Gauge to monitor brain activity before and after aerobic exercise. The objective of the study was to determine if there were short-term and/or long-term effects of aerobic exercise.  The data suggests that there are short-term effects and some improvements in performance on the tasks when comparing metrics obtained after exercise to before exercise.  For this individual, aerobic exercise was a regular part of daily routine, there was no long-term effect detected over the relatively short duration of the study.

The Empirical Analysis

The relationship between income and consumption is one of the most important subjects of economics that became the subjects of many study. In this study, Absolute Income Theory of Keynes for Turkey is predicted by using the data in period 1987 – 2012 and the method of cointegration. Before the econometric analysis, the function of consumption, consumption theories, studies involving these theories and its critics were examined. After that, variables were examined the unit root situations. Two variables do not take action together and it is seen that they do not affect each other when the long term relations and the short term dynamics are examined.

The Relationship

Summary. Two cohorts of Bos indicus crossbreds were studied to determine the relationships between temperament and growth in a feedlot and commercial carcass characteristics. Prior to entry to the feedlot, one cohort received intensive, short-term training at weaning but minimal handling before and after weaning, while the second cohort received similar training at weaning and also experienced a 4-month period of relatively intense handling immediately before entering the feedlot. Both cohorts entered the feedlot at similar ages. Temperament was recorded as the animal’s flight speed, which is the time taken for the animal to cover 1.7 m after leaving a weighing crush, with fast times indicating animals that have poor temperaments. Average flight speed scores of animals in the 2 cohorts differed substantially, with 51 and 12% of animals in cohorts 1 and 2 respectively having fast flight speed scores. Conversely, 23 and 69% of animals in cohorts 1 and 2 respectively had slow flight speed scores and could therefore be regarded as docile. In the first cohort, animals with slow flight speeds gained weight more rapidly (P<0.05) to achieve heavier slaughter and carcass weights (P<0.05) than animals with fast flight speeds. The relationship between flight speed and growth in the feedlot in the second cohort was not significant, although animals with the fastest flight speeds in that cohort had the lowest liveweight gains. Docile animals in both cohorts had comparable liveweight gains in the feedlot. These results suggest that animals with slow flight speed scores (good temperaments) may grow faster in a feedlot than animals with faster flight speed scores (poorer temperaments), regardless of whether the favourable scores result from intensive, long-term handling or because the animals are naturally docile. There was no relationship in either experiment between flight speed and fat thickness or carcass bruising, when bruising was scored simply as presence or absence of bruising. A negative relationship was evident between flight speed score and dressing percentage in the second cohort (P<0.05). The relationship between flight speed and dressing percentage was not significant in the first cohort. It is suggested that feedlot operators could select potential feedlot animals on the basis of temperament before entry to the feedlot to improve performance in the feedlot.

The Relationship

The relationship between level of debt and the companys performance remains an important unsolved issue in the field of financing. It is very important to know how Chinas listed companies manage their capital towards business growth. This paper investigates the impact of the capital structure on corporate performance of a sample of 711 listed companies on the Shenzhen Stock Exchange in China in 2014. The results indicates that there is a positive relation between financial leverage and corporate performance as well as there is a positive impact that the mixture of long-term debt and short-term debt (using total debt). This would help decision maker in the companies to finance firms operation in the both periods. On the other hand, the short term debt has a negative relation and impact on corporate performance compared to the changing in firm size which cannot change in the profitability of firms.

The Impact

This paper analyzes the impact of fieldwork on the development of students’ mental models concerning glaciers and their effects on the landscape. Data were collected by means of an open-ended questionnaire that was administered to 279 pre-service teachers before and after an educational field trip, which analyzed its impact on short-term and long-term outcomes. In general, students’ mental models about how glaciers function and how they create landforms are relatively simplistic and incomplete. Students are unaware of the major erosional properties associated with glaciers and many of them do not specify that glaciers are bodies of ice that have a tendency to move down slope. The analysis of the data yielded four mental model categories. Fieldwork influenced the short-term effects on mental model development even though its positive impact decreases over time. Mental models including scientific views were only found in the post-instruction group. On the other hand, the pre-instruction group was strongly influenced by a catastrophic event that occurred in the region in 1959 (the Ribadelago flooding), which interferes with students’ mental reasoning on the formation of landscape features. This way of thinking is reinforced and/or mixed with a religious myth (Villaverde de Lucerna legend), which also invokes a catastrophic origin of the lake. In this case, this includes mystic flooding.

Immigrant Men

International migration of couples is rising. Still, there is little evidence on men’s and women’s domestic work hours before and after migration. This is despite the fact that domestic work provides deep insights into family life and, for migrants, is directly linked to integration. Therefore, this study examines how immigrant men and women change their domestic work hours following migration, using data from the German Socio-Economic Panel (SOEP). Our results show that domestic work hours increase for both genders after immigration. However, men are more responsible for running errands than women in the first years after migration. In the long term, the gender gaps return to the pre-migration state, with women shouldering a greater load than men. Accordingly, this study shows that migration only has a short-term impact on couples’ division of domestic work.

Abstract Interventions using exercise video games, or exergames, have shown short-term cognitive and physical benefits to older adults, though long-term effects are less promising. Enjoyment of exergames may promote exergame use after the intervention period, though little work has examined older adults’ views of exergames before and after gameplay experience. We invited 20 older adults between 65 and 84 years of age (M=73.30, SD=5.95) to play two Xbox Kinect games, Just Dance and Kinect Sports Rivals, for twenty minutes. In our presentation, we will present qualitative and quantitative findings of this pilot study, including findings that older adults reported that they were not likely to play similar exergames in the future and that they did not find the exergames to be more fun compared to other ways of exercising. We will discuss implications for game design and research relevant to game developers, manufacturers, and researchers. Part of a symposium sponsored by Technology and Aging Interest Group.

Abstract Background To present a surgical technique for the treatment of intradural extramedullary (IDEM) tumors by using endoscopically controlled surgery with open hemilaminectomy technique. Methods In this study, 20 patients with 22 IDEM tumors were enrolled. An endoscopically controlled surgery with open hemilaminectomy was employed to remove the tumors. Data related to clinical symptoms and medical images before and after surgery were collected for perioperative evaluation and follow-up analysis. Results All the tumors in 20 patients were well removed. The clinical symptoms were significantly reduced in all the patients as well. The short-term follow-up data showed that there was no tumor recurrence or spinal deformity. Conclusion The endoscopically controlled surgery with open hemilaminectomy technique provided favorable exposure and satisfactory resection to the IDEM tumors. It may be an effective surgical method for treating IDEM tumors. Larger samples and longer follow-up data are needed to verify its long-term effectiveness.

The Relationship

Multicellular eukaryotes have evolved complex homeostatic mechanisms that buffer the majority of their cells from direct interaction with the external environment. Thus, in these organisms long-term adaptations are generally achieved by modulating the developmental profile and tissue specificity of gene expression. Nevertheless, a subset of eukaryotic genes are still involved in direct responses to environmental fluctuations. It is the adaptative responses in the expression of these genes that buffers many other genes from direct environmental effects. Both microevolutionary and macroevolutionary patterns of change in the structure and regulation of such genes are illustrated by the sequences encoding α-amylases. The molecular biology and evolution of α-amylases in Drosophila and other higher eukaryotes are presented. The amylase system illustrates the effects of both long-term and short-term natural selection, acting on both the structural and regulatory components of a gene–enzyme system. This system offers an opportunity for linking evolutionary genetics to molecular biology, and it allows us to explore the relationship between short-term microevolutionary changes and long-term adaptations.Key words: gene regulation, molecular evolution, eukaryotes, Drosophila, amylase.
