Higher Education Leadership and Management: From Conflict to Interdependence through Strategic Planning

Institutional leadership and management are two entirely different, yet intimately intertwined, aspects of the overall effective functioning of a higher education institution (HEI). This paper is intended to (1) define and differentiate between the two concepts, (2) critically discuss their importance and vital interdependence, (3) discuss circumstances that can create conflict or compatibility between these concepts, (4) critically examine models of strategic planning and suggest a better approach to this process, and (5) offer suggestions for the improvement of both leadership and management in the context of co-existence within a redefined strategic planning environment.     

The learning of response patterns in choice situations

This study presents a theory by which to understand how pigeons learn response patterns in simple choice situations. The theory assumes that, in a choice situation, patterns of responses compete for the final common path; that the competition is governed by two variables, the overall reinforcement probability obtained by emitting the patterns,T, and the differences in reinforcement probabilities among the patterns,D; and that the ratioD/T determines the final strength of specific response patterns. To test these predictions, three experiments were run in which pigeons were more likely to receive food when they pecked the momentarily least-preferred of three response keys. On the basis of previous research, it was predicted that the birds would be indifferent among the keys (molar aspect) and would also acquire a response pattern that consisted of pecking each key once during three consecutive trials (molecular aspect). The present theory went further and predicted that the strength of that pattern would increase with the ratioD/T. In the first two experiments,D was manipulated whileT remained constant, and in the third,T was manipulated whileD remained constant. The results agreed with the theory, for the strength of the response pattern increased withD and decreased withT, whereas overall choice proportions were always close to the matching equilibrium.     

Developmental Achievements of 7‐year‐old Children in Poland in the Light of International Tests and the Requirements of the Polish Language School Program

The language competence and reading comprehension of 406 7‐year‐old children are examined in the research discussed in this article. The children were tested using comparative tests as part of an international project conducted in 14 countries and sponsored by the IEA and the High Scope Research Foundation in Ypsilanti, USA. The discussion here relates only to a part of this wider research and focuses upon the aims and contents of Polish language teaching in grades I—III of the Polish primary school.     

Gender and Management in HEIs: Changing organisational and management structures

This paper reports on the second phase of a multi-country study examining cross cultural perspectives of gender and management in Higher Education Institutions (HEIs). It examines the broader labour market context and legislative frameworks for higher education in each country and then analyses the literature on women in university management. The paper presents the findings of research with male and female senior managers about their perceptions of women as HEI managers within changing organisational and management structures. It concludes that although HEI’s are now largely aware of barriers to women getting into and on in senior management, they have not addressed the organisational structures and cultures that perpetuate this inequity.

     

Alternative assessment of knee joint muscle balance of soccer players through total work-based hamstring: quadriceps ratios

Isokinetic hamstring-to-quadriceps (H:Q) ratios are frequently used to assess knee muscle strength imbalances and risk of injuries/re-injuries. The use of peak torque (PT) or total work (TW) to estimate joint stability may lead to different results because of the differences between these two neuromuscular variables. Thus, the current study aimed to compare the conventional and functional H:Q ratios calculated by PT and TW. Ninety-three male professional soccer players from Brazilian first division teams performed isokinetic concentric and eccentric contractions of the quadriceps and the hamstrings at 60°/s. Muscle strength balance was calculated using the conventional torque ratio (CTR) and conventional work ratio (CWR), functional torque ratio (FTR) and functional work ratio (FWR) were highly and moderately correlated between them (r?=?0.83 and r?=?0.73, respectively). The Wilcoxon statistical test revealed significant differences between CTR and CWR, as well as FTR and FWR (p?T-test demonstrated significant differences in mean CTR–CWR and FTR–FWR, whereas Bland–Altman plots showed non-consistent bias. In addition, the chi-square test demonstrated significant differences between players below the conventional reference values and functional reference values (p?相似文献   

Sleep restriction and degraded reaction-time performance in Figaro solo sailing races

Abstract

In solo offshore sailing races like those of the Solitaire du Figaro, sleep must be obtained in multiple short bouts to maintain competitive performance and safety. Little is known about the amount of sleep restriction experienced at sea and the effects that fatigue from sleep loss have on sailors’ performance. Therefore, we assessed sleep in sailors of yachts in the Figaro 2 Beneteau class during races and compared response times on a serial simple reaction-time test before and after races. Twelve men (professional sailors) recorded their sleep and measured their response times during one of the three single-handed races of 150, 300 and 350 nautical miles (nominally 24–50 h in duration). Total estimated sleep duration at sea indicated considerable sleep insufficiency. Response times were slower after races than before. The results suggest that professional sailors incur severe sleep loss and demonstrate marked performance impairment when competing in one- to two-day solo sailing races. Competitive performance could be improved by actively managing sleep during solo offshore sailing races.     

Polymorphic response patterns under frequency-dependent selection

In a discrete-trials procedure, a frequency-dependent schedule shaped left-right choice proportion toward various equilibrium values between 0 and 1. At issue was (1) whether pigeons match when the overall reinforcement probabilities for two responses depend inversely on their recent frequency, and (2) how pigeons meet the schedule constraint in terms of local responding. That is, do they respond quasi-randomly (Bernoulli mode), or do they learn the stable pattern of the schedule (stable-pattern mode)? Molar choice behavior always tracked the equilibrium solution of the schedule, but the molecular response patterns varied substantially. Markov chains applied to the data revealed that responding was generally intermediate between the memoryless Bernoulli mode, and the perfect memory stable-pattern mode. The polymorphism of molecular patterns, despite molar regularities in behavior, suggests that (1) in order to engender the Bernoulli or stable-pattern modes, the reinforcement rule must strongly discourage competing response patterns (e.g., perseveration), and (2) under frequency-dependent schedules, molar matching is apparently not the outcome of momentary maximizing.     

Inferencias causales y clasificación: su relación en niños de 4–7 años

Resumen

La presente investigación analiza la relación entre la adquisición de la clasificación y la ca- pacidad para realizar inferencias causales. Además, se pretende comprobar en qué medida los contenidos de las historias causales (en términos de animado/inanimado, de los antecedentes y los consecuentes) provocan diferencias en la ejecución. Participaron 70 niños de 8 centros públicos de EGB de Murcia, el rango de edad oscilaba entre 4;0 y 7;10. Los resultados indican cómo a medida que los sujetos dominan la clasificación muestran una mayor capacidad para realizar inferencias causales. No aparecen diferencias en la ejecución debida a los contenidos de las historias. Finalmente, se propone un modelo causal, a partir del modelo de equilibrio de la teoría de Piaget, sobre el desarrollo de las inferencias causales.
