Considerations on the design of a professional education of counselorsSome of the recently published articles about supervision-professionalizing are reflecting only sociological or psychological conceptions in order to describe and analyze professionality. In this article the authors discuss some of the mostly neglected points of view out of pedagogic and microsociologic professionalization-research (professional self, researching attitude). The existing requests of competence for supervisors are examined in order to test their teaching ability. Furthermore the content designs and didactic strategies for future counselor’s education are considered. 相似文献

Let G=(V,E) be a graph without an isolated vertex. A set D⊆V(G) is a k
-distance paired dominating set of G if D is a k-distance dominating set of G and the induced subgraph 〈D〉 has a perfect matching. The minimum cardinality of a k-distance paired dominating set for graph G is the k
-distance paired domination number, denoted by γ
p
k
(G). In this paper, we determine the exact k-distance paired domination number of generalized Petersen graphs P(n,1) and P(n,2) for all k≥1. 相似文献

This paper developed an exact method of random permutations when testing both interaction and main effects in the two-way
ANOVA model. The method of this paper can be regarded as a much improved model when compared with those of the previous studies
such as Still and White (1981) and ter Braak (1992). We further conducted a simulation experiment in order to check the statistical
performance of the proposed method. The proposed method works relatively well for small sample sizes compare with the existing
methods.

Utilizing data from the Census of India, this study compared child sex ratio in rural and urban regions of India and analyzed
whether the child sex ratio was associated with mother’s education level. The child sex ratios in the rural and urban regions
throughout India were analyzed using the two-sample and paired Student’s t-test. Further, the Chi-square test for trend in binomial proportions was used to assess the association between child sex
ratios and mother’s education levels in rural and urban areas. Analysis of the data showed that there was a significant difference
between the child sex ratios in rural areas versus urban areas. In addition, the Chi-square test for trend showed that there
was a significant association of the child sex ratio and the educational levels of their mothers. This trend occurred in both
rural and urban areas. 相似文献

We introduce two extreme methods to pairwisely compare ordered lists of the same length, viz. the comonotonic and the countermonotonic
comparison method, and show that these methods are, respectively, related to the copula T
M
(the minimum operator) and the Ł ukasiewicz copula T
L
used to join marginal cumulative distribution functions into bivariate cumulative distribution functions. Given a collection
of ordered lists of the same length, we generate by means of T
M
and T
L
two probabilistic relations Q
M
and Q
L
and identify their type of transitivity. Finally, it is shown that any probabilistic relation with rational elements on a
3-dimensional space of alternatives which possesses one of these types of transitivity, can be generated by three ordered
lists and at least one of the two extreme comparison methods. 相似文献

The European bond market is made up of many segments characterised by varying levels of liquidity and of pre- and post-trade
transparency. The possibility of extending the transparency provisions envisioned in the Directive 2004/39/EC, disciplining
the functioning of markets in financial instruments in Europe (MiFID), from the equity to the bond market is currently being
discussed. This poses risks to the status quo through trading fragmentation and strong negotiating power of a few large dealers,
particularly with respect to small retail investors. The main conclusion of the paper is that if MiFID transparency rules
are to be extended to the bond market, this must be “real” transparency, meaning pre-trade dissemination of real-time executable
prices and a transparent order book. Under current provisions, this kind of information is available if not directly to everybody,
at least directly to dealers and indirectly to professional and retail clients through business-to-business electronic platforms. 相似文献

Nowadays, it is popular that the dealer makes profits by selling a kind of discount coupons, which can be used as money to
purchase commodities with total cost less than or equal to the face value of the coupon. We can purchase a coupon at a price
of 0<s≤1 times its face value and the number of potential purchasable coupons is a given integer l. The customer has the option to buy the goods by cash completely or by a discount coupon. However, each piece of goods can
only use one coupon and the coupon used must have enough balance for the goods. The objective is to minimize the total cost
for purchasing all the goods. In this paper, we reduce the problem to a special bin packing model. We consider the online
problems for all 0<s≤1 and 1≤l≤∞. We present optimal online algorithms for all 0<s≤1 when l=∞ and l=1. For 2≤l<∞, we give both a lower bound and an algorithm, and show the algorithm is optimal for l=2.
