CONFLICT MANAGEMENT OF ENTERPRISE
No full textVsak dan slišimo, beremo in se pogovarjamo o konfliktih med državami, političnimi strankami, družinskimi člani, udeleženci v prometu. Konflikti so prisotni v našem vsakdanjem življenju. Nobena izjema niso konflikti na delovnem mestu v organizaciji. Pogosto te konflikte dojemamo kot nujnost, s katerim se moramo sprijazniti. V organizacijski literaturi beremo o konfliktih kot stalnem pojavu, o njihovih lastnostih, vzrokih, vrstah, posledicah, njihovem premagovanju ali celo spodbujanju, o ravnanju z njimi. Naučili smo se, da konflikti ne prinašajo le negativnih posledic, temveč da so lahko koristni za razvoj podjetja in razvoj zaposlenih v njem.
V diplomskem seminarju smo se usmerili le v ožji del preučevanja konfliktov: v samo nastajanje in potek organizacijskih konfliktov v organizacijskih procesih. V prispevku smo se omejili na konflikte med posamezniki, ki izvirajo iz razmerij med njimi kot člani organizacij. Vse ugotovitve smo smiselno razširili tudi na konflikte med skupinami in konflikte v skupini.
V diplomskem seminarju smo najprej prikazali razumevanje konflikta. Poudarili smo nujnost konflikta v vsakem organizacijskem razmerju v podjetju in opredelili tisto vrsto konfliktov, ki je predmet obravnave. Nastajanje in potek konfliktov smo prikazali v neformalnih in formalnih organizacijskih procesih. Prikazali smo usklajevanje ali koordinacijo kot proces, ki vpliva na potek konflikta in vlogo managementa pri reševanju oziroma upravljanju s konflikti.
V praktičnem delu diplomskega seminarja smo prikazali in dokazali obstoj konfliktov v izbranem podjetju. Vodstvo v izbranem podjetju se po rezultatih anketnega vprašalnika, ki smo ga pripravili sicer aktivno ukvarja s upravljanjem konfliktnih situacij, a prostora za izboljšave je mnogo. S teoretičnimi predlogi kako izboljšati upravljanje s konflikti smo del rešitev za izbrano problematiko predlagali tudi sami.In many cases, conflict in the workplace just seems to be a fact of life. We\u27ve all seen situations where different people with different goals and needs have come into conflict. And we\u27ve all seen the often-intense personal animosity that can result.
The fact that conflict exists, however, is not necessarily a bad thing: As long as it is resolved effectively, it can lead to personal and professional growth. In many cases, effective conflict resolution can make the difference between positive and negative outcomes.
The good news is that by resolving conflict successfully, you can solve many of the problems that it has brought to the surface, as well as getting benefits for company that you might not at first expect.
However, if conflict is not handled effectively, the results can be damaging. Conflicting goals can quickly turn into personal dislike. Teamwork breaks down. Talent is wasted as people disengage from their work. And it\u27s easy to end up in a vicious downward spiral of negativity and recrimination.
The discussion needed to resolve conflict expands people\u27s awareness of the situation, giving them an insight into how they can achieve their own goals without undermining those of other people.
To calm these situations down, it helps to take a positive approach to conflict resolution, where discussion is courteous and non-confrontational, and the focus is on issues rather than on individuals. If this is done, then, as long as people listen carefully and explore facts, issues and possible solutions properly, conflict can often be resolved effectively. And that is the point of managing conflicts

Soybean yield potencial in petric plinthosols: climate and economic interactions.
No full textABSTRACT: Soybean production in central Brazil predominantly occurs on ferralsols. However, increasing global demand has driven expansion into marginal areas with less suitable soils, particularly petric plinthosols. These soils present significant agronomic challenges, especially their heightened vulnerability to climatic variability. Nevertheless, some regions with petric plinthosols, such as parts of Tocantins state, have achieved surprisingly high soybean yields. Despite this production potential, research on soybean cultivation in petric plinthosols are still limited. Our study addresses this knowledge gap by evaluating how environmental conditions and management practices, particularly sowing dates, affect soybean yields in petric plinthosols compared to ferralsols. We also developed economic indicators to support sustainable production decisions. The results demonstrated that while high yields are achievable in petric plinthosols, these soils exhibit greater climate sensitivity than ferralsols. Environmental factor such as air humidity, mainly in the reproductive phase, is a limiting factor for higher yields. Notably, our economic analysis revealed that cost management impacts profitability more substantially than yield improvements, even under unfavourable conditions. This finding suggests that strategic farm management could make petric plinthosol cultivation economically viable despite their agronomic constraints

Accurate High-Frequency Modeling of the Input Admittance of PWM Grid-Connected VSCs
No full textThis article addresses high-frequency admittance modeling of current-controlled voltage source converters (VSCs). Recent studies have shown that harmonic instability may also occur at frequencies above the Nyquist frequency. To form an accurate multiple-frequency model in this frequency range, sidebands that originate from modulation and sampling must be examined. In this article, an accurate small-signal model is developed taking into account an adequate digital pulsewidth modulator (DPWM) representation, which allows to predict dependence of the frequency response on the steady-state dc (SS-dc) operating point. It is shown that when center-pulse sampling is implemented, pulsewidth modulation sidebands do not create additional loops leaving only sampling sidebands to be considered. Using the same approach as for SS-dc operation, a model that accurately represents admittance measurements during sinusoidal ac (S-ac) operation is developed. Its basis is a novel DPWM model suitable for S-ac regime, which allows to predict dependence of the VSC’s input admittance on the grid voltage magnitude. Experimental and simulated admittance measurements, performed on a single-phase two-level VSC during various SS-dc and S-ac regimes, match with the proposed models up to twice the sampling frequency
Analysis and DSP Implementation of Multi-sampled Three-Phase Current Controllers
No full textThis paper presents a method for current control of three-phase systems, realized using the multi-sampled pulse-width modulator (MS-PWM). The feedback signal is highly oversampled and filtered to obtain its average value with high noise suppression. Independently, the control update rate is chosen to be higher than double the switching frequency, which reduces delays due to calculation and digital modulation. In this way, the proposed strategy offers improved dynamic response compared to standard double-update PWM, while offering a high quality feedback signal, robust to noise sampling and aliasing. The analysis is verified using a standard digital signal processor TI f28379d and a Typhoon HIL 402 hardware-in-the-loop system that emulates an electric drive with a high-speed BLDC motor
Small-Signal Modeling of Phase-Shifted Digital PWM in Interleaved and Multilevel Converters
No full textIn this article, small-signal modeling of digital pulsewidth modulators (DPWMs) used in multicell voltage source converters (VSCs) is addressed. In addition to sampling and computation, DPWM introduces delay, which impairs VSC's dynamic performance and robustness. In order to take into account the influence of modulation delay, an accurate small-signal representation of DPWM is necessary. Here, modeling of multisampled bipolar and unipolar phase-shifted DPWMs for single-, double-, and multi-update strategies is presented. The simplest multilevel modulation of single-cell full-bridge VSCs, unipolar DPWM, is also covered by the analysis. The derived operating-point-dependent small-signal DPWM models are verified using simulated and experimental frequency response measurements up to four times the Nyquist frequency. Comparisons are also made with the models conventionally considered in the literature. Additionally, an approximate method is presented to model the influence of dead time on DPWM's small-signal dynamics. For the purposes of showcasing the importance of the proposed DPWM models, high-frequency admittance of a VSC employing multisampled multiupdate unipolar DPWM is modeled and verified in simulations and experiments
Models for Stationary Noise Propagation in Multi-sampled PWM Power Electronic Control Systems With Decimation
No full textThis article derives models for stationary noise propagation in multi-sampled control systems, taking decimation into account. It is explained how the decimation is either included deliberately, in case of multi-rate control, or inherently by the modulator, in case of multi-sampled pulsewidth modulation (MS-PWM). In the latter case, the decimation rate is determined by the switching frequency and the number of pulsewidth modulation (PWM) carriers. The proposed models are then used for digital filter design, with a goal of suppressing the decimation-related aliasing and attenuating noise, while considering the imposed impact on the dynamic response. The theory is verified in simulations and experimentally, confirming the assumed decimation mechanisms as well as the potentiality of MS-PWM to jointly enable high-bandwidth control and strong noise suppression. The experimental measurements are conducted on two hardware prototypes, comprising two-level and three-level dc-dc buck converters
Mass Production Cage for Aedes albopictus (Diptera: Culicidae)
No full textMass production is an important component of any pest or vector control program that
requires the release of large number of insects. As part of efforts to develop an area-wide program
involving the sterile insect technique (SIT) for the control of mosquitoes, the Insect Pest Control
Laboratory of the Food and Agriculture OrganizationÐInternational Atomic Energy Agency (FAOÐ
IAEA Joint Division) has developed a mass production cage (Aedes MPC) for brood stock colonies
in a mass production system for Aedes albopictus (Skuse, 1895). A preliminary experiment using
Plexiglas cages was carried out to estimate the impact of cage volume on egg productivity. Transparent
Plexiglas cages of different dimensions but loaded with the same adult density were tested. Egg
productivity (number of eggs laid per adult female) and adult survival were recorded and analyzed.
According to the results, the optimal volume of 100 liters has been chosen to develop the Aedes MPC.
The numbers of adults introduced into the Aedes MPC did not affect the egg production and adult
survival in comparison with the Plexiglas cage experiment data, conÞrming the possible use of Aedes
MPC for mass-rearing procedures. Finally, the modiÞcation of Aedes MPC and creation of a new
prototype model of MPC (Anopheles MPC) to effectively contain Anopheles arabiensis (Patton, 1905)
adults is discussed with major changes pioneered to oviposition devices and systems for automatic
collection of the eggs
