Each member of the team had to name an unlimited number of team-mates according to two choice criteria of emotional type and two of functional type. A method was adopted that is ana- logous to metric multidimensional scaling with an oblique transformation of the initial dimensions. The first generation gave two and the second five taxonomic dimensions that differentiate the players according to the used choice criteria. The resu lts confirm the known fact on the change of individual status within the group due to changes in group membership.

INTRODUCTION The mi ero-social structure of sports groups plays a significant role in the successfulness of the team. Namely, the successfulness of the team does not depend only on the fact that it consists of the best individuals, but also on the best possible interaction between them. A successful social integration of the team members, coaches and team management enables the team to achieve stable results in tirne and, at the same tirne, a higher tolerance towards frustration. Ali this is especially true for top sports teams. Therefore the knowledge on group dynamics should become an integral partof the programming and control of training in sport. The relation between the formal and the informal structure of the group can have a crucial character for the team's success. Of course, the specificities of the individual sport or kinesiological activity play a significant part in all of this. The resu lts presented here deal with two generations of a basketball team, which both placed first in their competition level. Therefore it was of interest to analyse the micro-social structure in such teams taken as whole entities and also to analyse what happens with those players that were present in both generations. This means checking if their position in the team changes in accord with the change in the team's membership, i.e. with the partingand coming of team players. When the matter of studying micro-social groups and their dynamics is discussed, two questions on the reasons and needs for such research can be posed. The first is, why study small groups and the second why study (small) sports groups. 1 n answer to the firstquestion the following reasons might be sta- ted: pragmatic, socio-psychologic, sociologic and comparative (Mills, 1967). In answer to the second question, four valid reasons can be given (Schafer, 1966) for their research, as sports groups have com- mon structural characteristics favourable for gener- alisation. The first reason is, thatthe sports group is a "natural" group and not an artificial one, or even a " laboratory" group. The second reason deals w ith the possibility of keepingthe variables that represent the constant of group's micro-structure (size of the group, structure of roles, rules of conduct) under control. The th i rd reason is in the existence of a com- mon goal, in the realisation of which we can monitor the development of the relations of competitiveness, homogenisation or conflict, outside the group or within the group. And at the end, studies of sports groups enable exact measuring of group effects, w hich can be quantified, seldom so well in anyother 27 kind of group, for example in terms of the number of committed errors, number of lost or gained balls, etc. An overview of the existing literature according to this criterion leads to the following conclusions: works that belong to the functional istic theories deal with the relation sportsman-coach, tryingto give this relation a widersocial-system frame (Hendry, 1973), or deal with the identification of methodological problems that emerge when one studies small groups in sport with functional and social structural analysis (Luschen, 1986). Fram the olderworks, one should point to those that study the relations between certain situational variables of competition and success and problems of group conformity (Myers, 1962). While doing so, the psychological and sociological variables are brought into balance, combining: personal aspirations of the players, their sociometric structure, cohesiveness and motivation in order to find an ideal team - in this case the ideal five in basketball (Klein, Christiansen, 1966, - all cited according to Petrovic, 1973). In works that belong to theories of (symbol ic) inter- actionism the problems in small groups in sport are treated above ali in relation captain-the other pla- yers, i.e. the problem of leadership, the nature of bringingaboutthe decisions in the group (Fine, 1986 and Kjeldsen, 1981 ), the role of the coach in relation to the result expectations from the spectators (Snyder and Spreitzer, 1979), or even the influence of the social structure on the inter-personal commu- nication in top female basketball teams (Koehler, 1982). In the case of authors that belonged, or sti li do, to marxist theory and its various variants, they mostly analysed the influence of co-operation, both on the leve! of individual-technical quality, and the moral- psychological criteria, on the successfu lness of sta te selections, or the influence of functional correlation on the cohesiveness of the group. In a similar way they also studied the influence of forma! and infor- mal leaders in basketball on the relations in the group and the succes~fulness of the group (Volkov, 1967; Stawiarski and Zarek, 1968; Mutafova, 1969 - ali cited according to Petrovic, 1973). To this theory belong also a whole series of studies by authors who enriched the methods for observi ng interpersonal relations with sociometric methods and data on the influence of the micro-social status on motivation, values, leve! of aspiration of the pla- yers and team management, differences in the ap- proaches to the game covnditioned by generation dif- ferences etc. (Petrovic, Siftar, 1970 and 1971, cited 28 by Petrovic, 1973; Šnajder, 1984; Šnajder and Hošek, 1985). Fu rther development of m icro-social research in the field of socio-dynamics of sports groups will to a large extent be made by the redefinition of the strategic interests in theoretical foundations, both by general sociology, as well as by sport sociology. It seems that the greatest obstacle in the development of general sociology, but also its special disciplines among wh ich we can cou nt also the sociology of sport, is the non-existence of a "general theory" . This situation has two interpretations among the researchers: some experience this asa lack which causes general discomfort and uncertainty in the operationalisation of the individual tasks, while others do not bu rden themselves with it. Therefore, while on one side it is felt that it is high tirne to bring some order into the great "conceptual and theore- tical chaos" which is the direct consequence of the non-existence of an all-encompassing "mega theo- ry", on the other, it is felt that the plurality of theo- retical paradigms in sociology is not only a fact, but also a desired state which promotes a diversification of possible research approaches. Th is change, i .e. the sh ifti ng and concentrati ng of the focus from macro-sociological approaches towards a, provisionally named, "individualistic sociology" is specially needed in those places where they are trying to free themselves - from a general point of view- the experience of a monistic approach of the marxisttheory. Thisshiftshould bringthe researchers freedom from the frustrations caused asa result of the domination of one ideological and theoretical orientation and enable the application of different approaches. The growth of " theoretical pluralism" will facilitate the acceptance of those approaches that favour the developmentof disciplines such a sociology of sport. We see its perspective precisely in the orientation to- wards theoretical approaches which facilitate the development of "individualistic sociology", such as symbolic interactionism and neo-interactionism and their different derivations: phenomenological ori- entations and especially "ethno-methodology" (Čal ­ darovic, 1990). In this way a connection might final - ly be made with the relevantglobal researches in the field of micro-sociology and specially also the soci- ology of sport. The aim of this paper is not so much to point at the need for studies on sports groups, because this is considered after forty years' research in this field no longer a d ilemma, but rather to show current limita- Zrinka Lučič, Nataša Viskič-Štalec, Zoran Žugič THE PROBLEM OF LEADERSHIP IN BASKETBALL tions and new approaches in micro-social research. In short, we see a possibility for a perspective research of sports groups in two directions: first, in generating a conceptual framework, which by ad- mission of several leading theoreticians of the soci- ology of sport (Loy, McPherson, Kenyon, 1978) stili does notexist, and second; in the removal of the till now noted shortcomings in the methodology of empirical research. Also, one should at the same tirne combine the existing research procedures, without regard to their conceptual origin (Adorno, Horkheimer, 1980). METHODS This study was carried out on members of a junior basketball team through two generations. In one, thirteen players were invo lved, in the other seven- teen. Both generation players were treated with the clas- sical method of sociometric measurement, that is the players were asked to name an unlimited number of co-players accord i ng to a certai n criterion. Four cri- teria of selection were used, two were of emotional type and two of functional type, formulated as attraction i.e. provoking positive tendencies. The nominations of the co-players were made by the fol- lowing questions: (1) Name those players with whom you would like to share a room during trainingaway from home. (2) Name those players you would confide in, if you had intimate problems. (3) Name those players you like to co-operate with during the game. (4) Name those players whom you think able to be the captain of the team. The analysis of the micro-social structure of a group of entities obtained on the basis of data on multiple choosing was performed by a method analogous to the method of metric multidimensional scaling (with an oblique transformation of the kept dimensions). The analysis was performed in the space of entity vectors, where each entity that performed a choice according to a certain criterion was treated asa se- parate variable and each chosen entity (by any mem- ber, including himself and according to any criteri- on) asa separate entity. The number of dimensions was determined in such a way as to reproduce as much information included in the data matrix, as there is information emitted by dimensions with an above-average non-centered variance. The starting matrix for determining the initial orthogonal solution was the matrix of the scalar products of the entities' vectors. Zrinka Lučič. Nataša Viskič-Štalec.

Below the dia- gonal we have the data on how the players agree w ith the others in their choices. It can be seen that no generation shows a great number of choices by ali four criteria. In the first generation (table 1 A) the highest number of choices goes to player #9, who received 31 choices from a possible 52 (if we turn this into a relative number, for purposes of compa- rison with the second generation, we get 0.60). Behind him, we have players #7 (0.54), #3 (0.44), #11 (0.37) and the rest achieving between 0.21 (#12) and 0.08 (#2) relative choices. The table 2A holds the characteristic values of the choice matrix and the proportions that explain the number of achieved choices in the first generation. Two latent dimensions were isolated, reproducing Zrinka Lučič , Nataša Viskič-Štalec, Zoran Žugič THE PROBLEM OF LEADERSHIP IN BASKETBALL 62.24% of the information on the relations in this generation of basketbali players, defined by four choice criteria. The first taxonomic dimension, obtained by a obli- min transformation of the initial orthogonal solution, explaining 52.45% of the choices is defined (table 3A) by all four choice criteria, even if the criteria "sharing a room" and "co-operation in the game" are more dominant than the other two. The second taxonomic dimension is defined by the emotional relationship, dependent on the existence of a so- called "unstable triad", where two members (who make upa diad) choose each other by ali criteria and the third occasionally chooses only one of them. It should be stressed that this is the only true diad in the whole team and that they caused the emergence of the second dimension. The dimension defined by these team members is almostorthogonal to the well structured first dimension (0. 13), but explains only 9. 79% of the choices in this group of basketbali pla- yers. The choices made in the first generation show the homogeneity of the group, as seen through the used choice criteria. The position of the player in this ge- neration is precisely defined already on the basis of the first latent dimension. These are player #9 who might be considered the leader of the group, then player #7 who has some cho ices less, but both are located on the extreme right pole of the first dimen- sion, with nuli projections on the second taxonomic dimension. The first dimension is also defined with, somewhat less but stili enough choices, by players #3; with a somewhat more strong position also on the second dimension and #11; on the negative pole of the second dimension. They are followed by players #13 and #12. Ali remaining players have very low choice counts on the first dimension, but have their posit ions along the second dimension. The best position there goes to players #5 and #4 and the associated triad member # 1 O. The players #8, #2, # 1 O and #1 are not interestingfor the oth- er players on none of the used choice criteria. 2. GENERATION OF BASKETBALL PLAYERS 1 n the second generation of basketbali players (table 1 B) the number of choices is less than in the first ge- neration. From the possible 68 choices, player #8 received 23 choices (0.34). After him, according to the number of choices by all four criteria, come play- ers #1 O (0.31 ), # 16 (0.29), #5 (0.28), etc. The relative number of choices for the remaining players varies from 0.24 (#11 ) to 0.07 (#12). These players were not often chosen in pair. The most frequent 31 pair-choice (triangle below the diagonal) were play- ers #8 and # 16, twelve times. Table 2B shows even five significant characteristic values for the second generation basketball players, together explain ing 65% of the information on the relations in the group, which is a lot less than in the first group. The increase in the number of dimen- sions did notalso bringaboutan increase in the per- centage of the explai ned choices. It is obvious that, as seen through the proposed choice criteria, the relations in the second genera- tion are more complex and that they condition the stratification of the players on the basis of five d i- mensions. The increase of the number of players from thirteen to seventeen isonly partlythe cause of this situation. This is seen also from the choices in ta- bles 1 A and 1 B. In the fi rst generation fou r players achieved a greater number of choices than the best in the second generation. The first taxonomic dimension explains 29.05% of the relations in th is group of players. It differentiates the players mostly according to thei r playing abilities and such personal characteristics (at least as per- ceived by the others) as to be su itable for acceptance of others' problems. The second taxonomic dimen- sion explains only 12.367% of the relations in the group. It differentiates the players according to all the analysed criteria, except "choice of captain". It is formed by the triad of players #13, #1 and # 17. The third taxonomic dimension explains only 8.605% of the information on the sociometric struc- ture of the members of the basketball team. It is de- fined by al l the used criteria. The fourth taxonomic dimension explains only 7.769% of the information on the relations in the group. It differentiates the players in accord to their playing abilities (as does the fi rst dimension) in combination with the criterion "room sharing". The fifth taxonomic dimension ex- plains even less than the previous one, only 5 .944%. It d ifferentiates players according to the criteria "room sharing" and "co-operation in the game", but without the criterion "captain" . It seems to be amatter of friendly relations between some mem- bers of the team, but without overestimating their playingabilitiesor thei r ability of being the captain of the team. In the second generation the best positions are tak- en by players #8 and # 16 on the first dimension, less good ones by players #13, # 17, #1 and #14 on the second dimension, player #5 on the third, # 1 O on the fou rth and # 11 on the fifth dimension. The other players are grouped around nuli choice values. 32 The first dimension in the second generation bas- ketball players is orthogonal to the second and equally correlated to ali the others. AII the other di- mensions are almostorthogonal to one another, ex- cept the fourth with the third and the fifth. The five best players: The used computer pro- gramme analyses the micro-social relations of each generation basketball players separately. However, if the five best players are present in the first, as well as in the second group of players, it is interesting to monitor their position in each of these two groups separately. In the tables these players carry the num- bers 1 through S. From the viewpointof micro-soci- ology the position of the individual in the group is determined by the milieu in which he finds himself. This is especially true of the special relations be- tween players in a sports game. So, firstly we will try to compare the position of each of these players in both groups and then try to extract some common explanation for ali five players: Player #1: both in the first and second generation has a small number of choices in dimension two. Player #2: does not hav_e any significant position, ei- ther in the first, nor in the second generation. Player #3: extremely highly figures in the firstgroup on dimension one, and somewhat lower also ondi- mension two. In the second generation he holds a prominent position only on dimension four. Obviously a significant drop of this player's position occurred on the hierarchical scale of the team. This is seen also on the basis of the values of communa- lities in the two analysed generations. Player #4: has a prominent position on the second dimension in the first generation. In the second ge- neration, he assumes such a position on the third dimension. Player #5: holds a high position on the second dimension in the firstgeneration, and an even high- er one on the third dimension in the second gene- ration. The value of the communality of this player is third by ran k in the second generation and only sixth in the previous one. It is the task of the coach to ana- lyse the reasons that bringaboutsuch changes in the status of players in the team, being caused by some events that can sometimes be influenced by the coach. CONCLUSION From the problems thatemerged from the tradition of empirical research of sociodynamics of small groups, especially sports groups, at least three should Zrinka Lučič, Nataša Viskič-Štalec, Zoran Žugič THE PROBLEM OF LEADERSHIP IN BASKETBALL be mentioned here (see in Petrovic, 1973) . lnto the first group fall those that are connected w ith a non- representative sample of respondents and/or vari- ables in existent researches. lnto the second group ali those that are a consequence of reducing the complete scale of ties and relations j ust to those that can be quantified through simplified metric proce- dures and techniques, such as the Moren sociogram and its modifications. lnto the third group we can classify problems that come from another simplifi- cation -due to strivings, evident in many researches, to bring atany cost into (cor)relation success in some kinesiological activity and the level of cohesiveness of a group, as an evident proof for constructinga the- ory of the team's success. In spite of ali, the performed research showed the value of such studies, which is above ali in the possi- bility of predicting those respondents that will spon- taneously emerge as "natura! leaders" of the team in the process of natura! selection.
