    Opis:
    The aim of study was to investigate the relationship between proactive coping strategies and the dimensions of identity formation, along with the role of biological sex and psychological gender as moderators for this relationship. We conducted analyses aimed at showing differences in terms of identity dimensions levels and proactive coping strategies used by a group of individuals with different biological sex and psychological gender. A group of 101 students from upper secondary schools (47 females, 54 males) from Pomeranian Voivodeship took part in the study. We used in our research The Dimensions of Identity Development Scale; The Psychological Gender Inventory and The Proactive Coping Inventory for Adolescents. We found, among others, that in the case of a proactive strategy, biological sex turned out to be a significant moderator in the relationship between this variable and identity dimensions: ruminative exploration, commitment-making and identification with commitment. In the case of instrumental support seeking, psychological gender turned out to be a significant moderator for the relationship between these variables and a part of identity dimensions. The obtained results show that, regardless of whether young people, in terms of characteristics that are stereotypically associated with biological sex, are described as aschematic (undifferentiated individuals) or schematic (sex-typed) when entering adulthood and attempting to constitute themselves, more often cope in a task-oriented manner by trying to create a set of information useful in difficult situations and aspire to obtain informational support from individuals in one’s own social network, who are regarded as safe people.

    Opis:
    The number of people suffering from type 2 diabetes has been growing recently. This chronic disease is connected with lower perceived quality of life and experiencing a lot of stressful situations. Some of these situations can be anticipated. Thus, it is possible to prepare oneself for future difficult situations by using proactive coping strategies. The aim of this research was to verify the level of satisfaction with various areas of life, the frequency of use of proactive coping strategies in the case of type 2 diabetes patients and healthy individuals, as well as mediation role of these strategies in the relationship between positive emotionality, cognitive curiosity and perceived quality of life. One hundred and seventy four persons took part in the research: 85 persons with diabetes and 89 healthy individuals. We used instruments with recognized psychometric properties: The Proactive Coping Inventory, The World Health Organization Quality of Life Instrument-BREF, PANAS Questionnaire and State-Trait Personality Inventory. The analysis of the results showed, among other things, that people suffering from type 2 diabetes are the least satisfied with their health, and the most with their treatment and knowledge about the disease. Healthy individuals are the most satisfied with the physical domain and one’s present life, whereas the least satisfied with the environmental domain. Both groups differ in terms of using proactive coping strategies. People with diabetes most often adopt a preventive strategy, whereas healthy individuals a reflective one. Two strategies turned out to be able to mediate in the relationship of positive emotionality and life satisfaction in the diabetes group. It was a strictly proactive and preventive coping strategy. No mediation effect was found in the group of healthy people. The results show that in the face of anticipated difficulties, people with type 2 diabetes try to protect their current resources by resorting to their existing knowledge, the level of which they are most satisfied with. The higher the positive emotionality/cognitive curiosity among people with type 2 diabetes, the higher their satisfaction with life, which is due to the fact, that they more frequently use proactive or preventive strategies to cope with stress.

    Opis:
    In middle adulthood the intensity of stress is significantly higher than in the preceding developmental period. This stress is particularly significant in the case of chronically ill women, including those with type 2 diabetes. In this group, the disease-related stress intensifies the difficulties generated by the decrease of age-related organismic resources and in many instances impairs the quality of life. Therefore, an ability to cope with difficult situations is of crucial importance. The aim of the research was to estimate the general level of life-satisfaction, as well as the frequency and effectiveness of proactive coping strategies in a group of middle adulthood women with type 2 diabetes compared to women not suffering from diabetes. The study was conducted with methods which have acknowledged psychometric properties (SWLS, WHOQoL - BREF, PCI) as well as a survey collecting sociodemographic data. Women suffering from type 2 diabetes are less satisfied with their prior and current life, health and the physical dimension of their lives and environment. Only partially do they employ proactive coping strategies different from those used by the women from the healthy group. For life-satisfaction in its various aspects it is particularly important for the diabetic women to more often use the strategy of reflective coping and to less often seek emotional support while using the strategy of preventive coping or avoidance. The proactive strategies directed at anticipated stress are connected with the level of life-satisfaction and considered to be health resources.

    Opis:
    Redundancy based methods are proactive scheduling methods for solving the Project Scheduling Problem (PSP) with non-deterministic activities duration. The fundamental strategy of these methods is to estimate the activities duration by adding extra time to the original duration. The extra time allows to consider the risks that may affect the activities durations and to reduce the number of adjustments to the baseline generated for the project. In this article, four methods based on redundancies were proposed and compared from two robustness indicators. These indicators were calculated after running a simulation process. On the other hand, linear programming was applied as the solution technique to generate the baselines of 480 projects analyzed. Finally, the results obtained allowed to identify the most adequate method to solve the PSP with probabilistic activity duration and generate robust baselines.

    Opis:
    Terminowa i sprawna realizacja przedsięwzięć budowlanych oraz redukcja czasu ich wykonania wpływają na efektywność ekonomiczną inwestycji i działalności gospodarczej wielu podmiotów zaangażowanych w proces inwestycyjny. Cechą specyficzną produkcji budowlanej jest znaczna podatność na oddziaływanie zmiennych warunków realizacji, dlatego też przy harmonogramowaniu nie powinno się pomijać wpływu oddziaływania czynników ryzyka. Wiele przedsięwzięć budowlanych składa się z powtarzalnych procesów, są to m.in. budowy osiedli domów mieszkalnych, budowy obiektów wysokich i wielosekcyjnych, dróg, tuneli, instalacji itd. W celu redukcji czasu ich wykonania obiekty te dzieli się na działki robocze, na których powtarzane jest wykonywanie procesów przez brygady robocze o odpowiednich kwalifikacjach. W przypadku, gdy działki różnią się wielkością i nie występuje zależność wprost proporcjonalna pomiędzy ich wielkością i pracochłonnością robót (jednakowa dla każdego ich asortymentu), na czas realizacji przedsięwzięcia oraz na inne parametry wpływa kolejność zajmowania działek przez brygady. W artykule została przedstawiona metoda wyboru optymalnego harmonogramu robót powtarzalnych realizowanych na działkach niejednorodnych w warunkach ryzyka i optymalnej permutacji działek roboczych. Analizowany problem opisano za pomocą modelu programowania stochastycznego z funkcją celu minimalizującą łączne straty finansowe spowodowane niedotrzymaniem terminu dyrektywnego przedsięwzięcia, wydłużeniem okresu zatrudnienia brygad i czasu realizacji poszczególnych obiektów, na skutek przestojów spowodowanych zjawiskami losowymi. Ze względu na probabilistyczny charakter parametrów rozpatrywanego problemu do jego rozwiązania zaproponowano procedurę bazującą na zastosowaniu metody symulacji komputerowej oraz algorytmów metaheurystycznych lub – w przypadku problemów o małej złożoności z niewielką liczbą działek roboczych – metody przeglądu zupełnego zbioru rozwiązań dopuszczalnych.
    Most scheduling methods used in the construction industry to plan repetitive projects assume that process durations are deterministic. This assumption is acceptable if actions are taken to reduce the impact of random phenomena or if the impact is low. However, construction projects at large are notorious for their susceptibility to the naturally volatile conditions of their implementation. It is unwise to ignore this fact while preparing construction schedules. Repetitive scheduling methods developed so far do respond to many constructionspecific needs, e.g. of smooth resource flow (continuity of work of construction crews) and the continuity of works. The main focus of schedule optimization is minimizing the total time to complete. This means reducing idle time, but idle time may serve as a buffer in case of disruptions. Disruptions just happen and make optimized schedules expire. As process durations are random, the project may be delayed and the crews’ workflow may be severely affected to the detriment of the project budget and profits. For this reason, the authors put forward a novel approach to scheduling repetitive processes. It aims to reduce the probability of missing the deadline and, at the same time, to reduce resource idle time. Discrete simulation is applied to evaluate feasible solutions (sequence of units) in terms of schedule robustness.
