This paper revisits the strategic selection of the bargaining agenda in a unionized industry with potential entry and decentralized negotiations for different competition modes. The incumbent chooses Right-to-Manage (RTM) or Efficient Bargaining (EB) considering two scenarios: (1) the agenda is imposed to the (potential) entrant (committed bargaining) and (2) the entrant can flexibly choose the agenda (flexible bargaining). In the mixed duopoly, the timing of the game is as follows: at stage 1, the EB firm bargains over wage and employment with its union, while the RTM firm bargains over the wage; at stage 2, the RTM firm chooses employment. This paper shows that the strategic selection of the agenda strongly depends on the interaction between the degree of market competition, the union’s power, and the convergence or divergence between parties on the agenda’s choice. This complex interaction leads to a very rich set of equilibrium outcomes, including multiple and even (as regards the union’s preferences on the agenda) asymmetric equilibria. Compared with alternative timings in the literature, this specification leads to substantial differences with flexible bargaining: EB emerges as equilibrium in Nash strategies for a noticeably increased set of cases.

<p align="center"><strong>ABSTRACT</strong><strong></strong></p><p>This paper investigates the selection of the bargaining agenda in a unionized industry with decentralized negotiations for different competition modes. The firms choose the agenda (right-to-manage, RTM, <em>versus</em> efficient bargaining, EB), considering alternative timing of the bargaining game in the case of mixed duopoly. In fact, the EB (RTM) firm can be either Stackelberg wage follower (leader) or Stackelberg output leader (follower). A two-stage game is developed in which the typology as well as the timing of the negotiations is endogenous. It is shown that, in pure strategies, no equilibria arise for a wide set of the parameters’ space while RTM appears as the unique equilibrium agenda for a different combination of the parameters; moreover, multiple, asymmetric equilibria emerge in a limited area of the parameters’ space. These results are in sharp contrast to the received literature in which EB can arise as an industry bargaining institution in equilibrium.</p><p align="center"> </p><p align="center">UN ENFOQUE DE TEORÍA DE JUEGOS PARA LA SELECCIÓN DE LA AGENDA DE NEGOCIACIÓN DEL OLIGOPOLIO SINDICAL</p><p align="center"><strong> </strong><strong>RESUMEN</strong></p>Este artículo investiga la selección de la agenda de negociación en una industria sindicalizada con negociaciones descentralizadas para diferentes modos de competencia. Las empresas eligen la agenda (negociación con derecho de administrar, NDA, frente a negociación eficiente, NE) considerando casos alternativos de la sucesión de eventos en el juego de negociación con duopolio mixto. De hecho, la empresa NE (NDA) puede ser seguidora de salarios Stackelberg (líder) o líder de cantidades Stackelberg (seguidora). Se desarrolla un juego de dos etapas en el que la tipología y el momento de las negociaciones son endógenos. Se muestra que en estrategias puras no surgen equilibrios para un amplio conjunto del espacio de los parámetros, mientras que NDA aparece como la agenda de equilibrio única para una combinación diferente de los parámetros; además, los equilibrios múltiples y asimétricos emergen en un área limitada del espacio de los parámetros. Estos resultados contrastan con la literatura existente, en la que NE puede surgir como una institución de negociación de la industria en equilibrio.

The success of any intercomparison exercise depends largely on participation and cooperation of a sufficient number of laboratories and the selection of a suitable suite of samples. Unless the latter is satisfactorily devised, the former cannot be guaranteed. The hierarchical nature of this study has necessarily resulted in a far more comprehensive set of sample types than has previously been employed. The exercise was structured to satisfy the following criteria: 1) to enable the participating laboratories to assess the experimental precision and accuracy of the component stages of the dating process; 2) samples should be typical of those routinely dated by the laboratories. This takes on a particular significance in Stage 1 where they should resemble as closely as possible the counting medium; 3) an objective statistical analysis of the results at each component stage of the study.

Abstract Existing research on mediation finds that mediation by a strong mediator is both more prevalent and more conducive to a negotiated settlement. However, why disputants select a weak mediator remains unclear. From the perspective of the uncertainty mechanism, the nature of mediation is a procedure for sharing private information and reducing disputants’ uncertainty regarding the resolve to continue fighting. Disputants can benefit from mediation through gaining a comparative advantage regarding uncertainty by focusing on either controlling the sharing of their own information or increasing their opponents’ sharing of information. With regard to these two strategic choices, this article argues that the selection of a weak mediator is more likely when disputants prefer controlling the sharing of their information to expanding their opponents’ information sharing. Correspondingly, three potential factors that influence the disputants’ strategic choice of gaining a comparative advantage regarding uncertainty are applied, namely, a previous mediation in the dispute; the dispute’s level of hostility; and the power disparity between the disputants. The author compiles data from the International Crisis Behaviour (ICB, 1918–2015) data set and the International Conflict Management (ICM, 1945–2003) data set for the empirical analysis. The results show that mediation by a weak mediator is more likely when it is the first time that the disputants have submitted to mediation in the dispute and when the dispute’s level of hostility is low. In some cases, a large power disparity between the disputants also makes the selection of a weak mediator more likely.

Writing anecdote text is a creative and productive process, meaning an ability that requires students to produce a product (writing) that aims to provide criticism/ satire accompanied by humor against an event that occurred. The fact that the ability to write anecdot text is still low, the difficulty in putting ideas and ideas into the main factor. The need for a model of learning with the use of media as a way to overcome these problems. Projects based learning assisted media meme are used based on literature review, which is a student-centered learning by applying the concept of the project (based on actual life that occurs) in order to solve the problem independently by using memes as a media that serves to clarify a message or content delivered. At the stage (1) the determination of fundamental questions about the events that occur (actual), (2) preparing the project plan (selection of data collection activities), (3) preparing a schedule (completion of activities), (4) monitoring project progress, (5) assessment of results, and (6) evaluation of experience (reflection of activities). This research aims to determine (a) the effectiveness of the model and (b) the effectiveness of the model in the experimental class (MIPA and IPS). The methodology used is a quasi experiment with 2 by 2 factorial research design. The results of research from data analysis, obtained (a) the difference in ability between the experimental class and control class students with N-gain experiments enter into medium category, while the N-gain controls enter into low category. (b) there is no difference ability in experimental class between MIPA and IPS class students. This shows that the model of Projects based learning assisted media meme effectively used in the class with the background of MIPA and IPS in SMA Negeri 15 Bandung. Keyword: writing anecdote text, project based learning, and media meme.

How to choose the optimal project portfolio based on the enterprise objectives is very important for the survival and development of an enterprise. However, the current portfolio analysis needs to be improved in the aspects of interaction effect analysis, multichoice target planning, and method simplicity and practicability. The method of portfolio selection proposed in this study takes into consideration the complex interaction within the portfolio, which makes up for the deficiency of the existing research on portfolio selection. This paper illustrates the application of the multichoice object programming method in the analysis of the combination of two-project and three-project interaction effects by a series of examples. The results show that the method is applicable in portfolio evaluation. The method of multichoice goal programming of the interaction effect provides the basis for enterprise to measure the complex relationship within the portfolio and also provides a new method and idea for the selection of the enterprise project portfolio.

AbstractMaking use of a Conjectural Variation model, the present note re-examines the subject of the firms’ profits ranking under different degrees of market competition in a unionized duopoly with industry-wide Efficient Bargaining (EB). It is shown that, while Cournot-like competition profits are always larger than Bertrand-like ones with separated wage negotiations, an uniform wage bargaining can lead to the appearance of the reversal.

This work proposes the evaluation of a set of algorithms of machine learning and the selection of the most appropriate one for the classification of segmented chromosomes images acquired using the Giemsa staining technique (G-banding). The evaluation and selection of the best classification algorithms was carried out over a dataset of 119 Q-banding chromosomes images, and the obtained results were then applied to a dataset of 24 G-band chromosomes images, manually classified by an expert of the Laboratory of Cytogenetic of the Children’s Hospital of Tamaulipas. The results of evaluation of 51 classifiers yielded that the best classification accuracy for the selected features was obtained by a backpropagation neural network. One of the main contributions of this study is the proposal of a two-stage classification scheme based on the best classifier found by the initial evaluation. In stage 1, chromosome images are classified into three major groups. In stage 2, the output of phase 1 is used as the input of a multiclass classifier. Using this scheme, 82% of the IGB bank samples and 88% of the samples of a bank of images obtained with a Q-band available in the literature consisting of 119 chromosome studies were successfully classified. The proposed work is a part of an desktop application that allows cytogeneticist to automatically generate cytogenetic reports.

Business operations in today's highly dynamic and changing environment require quick response and adaptation to new business conditions. In this context, the terms "outsourcing" and "freelancing" are emerging. Due to their characteristics and new approach in the business environment, they enable different concepts of organizing and creating new business models. This paper puts in focus the problem of freelance status in the labor market competition for a business engagement. It has the task of providing a scientific view of the opportunities offered to freelancers according to the attitudes of potential employers. From the standpoint of the employers in the Republic of Croatia, business practice has changed considerably from the previous emphasis on 'permanent employment' in the past decade to a more significant selection of outsourcing for specific jobs. Employees’ views are also noticeably changing, so a more significant selection of independence in some legal forms of employment can be observed. An exploration of the attitudes and experiences of the employers on the recruitment of freelancers for occasional or permanent jobs in various areas of activity was conducted. The fundamental question to which research has to answer is whether an employer will decide to hire a freelancer in specific jobs for which key knowledge or company information is needed. There are four variables are in focus: how employment of a freelancer depends on the activity the company is engaged, the market in which it operates, the size of the company and previous experience with hiring freelancers.
