Abstract Breeding output of geese, measured as the proportion of juveniles in autumn or winter flocks, is lower in years with a late onset of spring in some species, but higher in at least one other species. Here we argue that this is because the timing of spring affects different stages of the reproductive cycle differently in different species. Because the effects on 2 different stages are opposite, the combined effects can result in either a positive or a negative overall effect. These stages are the pre-laying, laying, and nesting phase on the one hand; and the hatchling, fledgling, and juvenile phase on the other hand. The first phase is predominantly positively affected by an early snowmelt, with higher breeding propensity, clutch size, and nest success. The second phase in contrast is negatively affected by early snowmelt because of a mismatch with a nutrient food peak, leading to slow gosling growth and reduced survival. We argue that recognition of this chain of events is crucial when one wants to predict goose productivity and eventually goose population dynamics. In a rapidly warming Arctic, the negative effects of a mismatch might become increasingly important.

Abstract This article draws on 22 interviews with Italian anti-speciesists to develop a sociological account of the quest for ethical consistency in the animal rights movement. The essay analyzes three relevant consequences of the search for consistency—identity extension, social segregation, and self-transformation—and discusses their impact on the activists’ lives. Consistency appears as both a source of self-gratification and a burden. On the one hand, self-gratification results from a sense of moral pride and the certainty of fighting for a just cause. On the other hand, the pursuit of a consistent lifestyle is highly demanding in terms of time and energy, and can have negative effects on the activist’s relationships with family and peers. While the paper adopts an individual-level perspective, it also examines how the findings might relate to vegan mobilization. It is argued that the findings might be generalizable to activists in other countries who face similar challenges.

The problem of the description of artificially present industrial noises which are available at operation of personal computers is considered in work. These noises have both positive and negative effects when protecting the information typed by the user by means of the USB keyboard interface. The difficulties that arise in this case are due to the fact that the indirect radiation of electromagnetic fields is observed during the operation of all elements of computer technology. On the one hand, the presence of these noises distorts the useful signal, which in turn prevents the attacker from detecting reliable information that is transmitted. On the other hand, these noises prevent the creation of appropriate measures to ensure complete protection when typing by a user of a personal computer. The paper proposes to consider industrial noise in the form of three random processes, which are described by Johnson distributions.

The discourse of globalization and its effects have been the most current topic in the field of economics in recent times. However, empirical research on the impact of globalization on companies, especially in transition countries, is very scarce. This paper focuses on the study of the impact of globalization on the performance of companies in Bosnia and Herzegovina by analyzing their interrelationships. The findings, in the case of companies in Bosnia and Herzegovina, have confirmed earlier findings about the double impact of globalization by showing, on the one hand, its positive effects and, on the other hand, the negative effects on the performance of the companies. Additionally, the research results have shown that negative effects are felt more strongly in the case of small and medium-sized companies than in the case of large companies.

The different interpretations of the holy texts of the Qur'an further broaden the horizon of Muslim understanding of the content of God's messages on the one hand. But on the other hand, the greater the interpretation if not accompanied by an attitude of openness will lead to idiologization (talwiin) to certain understandings arising from that interpretation. Such an idiologisation will elicit a blind and faithless fanatic attitude in religion. Violence in the name of religion and the various conflicts among fellow Muslims recorded in the history of Islam from the past until now is concrete evidence of the negative effects of an interpretation. Therefore this paper is present to provide a comprehensive picture of the recitation of the Qur'an.  Keywords: Al-Qur'an, Contemporary Tafsir, Interpretation  Abstrak Perbedaan penafsiran terhadap teks suci al-Qur’an semakin memperluas horizon pemahaman umat Islam tentang kandungan pesan-pesan Tuhan di satu sisi. Namun di sisi lain, semakin banyaknya penafsiran tersebut apabila tidak dibarengi dengan sikap keterbukaan akan menimbulkan idiologisasi (talwiin) terhadap pemahaman-pemahaman tertentu yang muncul akibat penafsiran itu. Idiologisasi tersebut akan memunculkan sikap fanatik buta dan ketertutupan dalam beragama. Kekerasan atas nama agama dan berbagai konflik antar sesama pemeluk Islam yang tercatat dalam sejarah Islam dari dulu hingga sekarang adalah bukti kongkrit efek negatif sebuah penafsiran. Oleh karena itu tulisan ini hadir untuk memeberikan gambaran yang komprehensif terhadap pembacaan al-Qur’an.  Kata Kunci: Al-Qur’an, Tafsir Kontemporer, Penafsiran

Intellectual property rights have a twin effect on the economic system.On the one hand they increase the incentives to the introduction of new technologicalknowledge. On the other they increase the costs of the generation ofnew knowledge because they limit the access to an indispensable input such asexisting knowledge. A tradeoff between such positive and negative effects canbe formalized so as to identify of the ‘correct’ levels of knowledge rents...

Purpose – The purpose of this paper is to examine the impact of the Group Representation Constituency (GRC) system on the governance of Singapore, particularly in terms of equity and inclusiveness, accountability, and participation. Design/methodology/approach – Historical review and election data from Singapore government web site are used. Findings – The GRC system seems to be friendlier and fairer toward ethnic minorities than the traditional system. The GRC system also encourages political parties to be ethnically more inclusive. On the other hand, however, the GRC system has negative effects on opposition parties. A government cannot be called “accountable” if it lacks fair competition and sufficient popular participation. Originality/value – The Singapore experience shows that, in practice, ethnic equality/inclusiveness and even political stability on the one hand, and participation and accountability on the other hand, can present conflicts. Which value should receive priority thus requires serious consideration.

INTRODUCTIONThe published literature on the topic of glacigenic sediments is both transdisciplinary and extensive.Table 1 shows the papers in this session but includes two papers shown, at the bottom of the Table, which were included in Session 1a. Nine out of the twelve papers listed deal with till as one of the soils, consequently this review concentrates on this particular soil type.BACKGROUNDGlacial soils of the Quaternary may be as old as 2 million years on the one hand and yet may be very recent on the other. In reality, most of the glacially-derived soils (at least in the mid-latitudes) derive from the Anglian stage of the Pleaistocene or younger, and therefore are less than 500,000 years old.Subsequent to deposition, Pleistocene soils may have experienced multiple episodes of vertical and horizontal ice-loading and unloading and the further combined effects of, for example, permafrost, freeze-thaw, oxidation, decalcification and weathering may all have contributed to the making of an end-product quite difference as an Engineering material from the original sediment.The generalised lowland glacial domain, within which these sediments are formed, classically embodies proglacial, subglacial, englacial and supraglacial components which, taken together, can produce complex superimposed till-outwash-till sequences.GRADINGIt could be argued, therefore, that textural and mineralogical criteria along are inadequate as a basis for the identification of difference till types due, mainly to the considerable overlap in this respect. Therefore as a basis for discrimating between various till types there has been increasing emphasis in the geological literature

Defects obtained during impact extrusion of EN AW-5754 aluminium alloy during cartridge case production were investigated. In cartridge cases produced from the one metallurgical heat pronounced tendency to earing after impact extrusion observed/appeared. On the other hand the earing in cartridge cases from the other heat was not observed. Presence of earing is due to local difference in materials flow during extrusion. This behaviour is atriduted to dfference in second phase particle distribution in used preforms (slugs).

In Ecuador 46.4% of households lack access to sewerage systems, and then much wastewater is discharged from sewerage into the environment untreated. On the one hand dry toilet systems present themselves as an optimal solution against this backdrop; they mitigate the production of black water, whilst having fertilizer as the end product. On the other hand, they tend to have a low acceptance level by potential end users. This problem of social acceptance is then further exacerbated in urban areas. In order to overcome this, the design of an ecological dry/semi-dry toilet was carried out in two phases. The first phase consisted of purely sociological research, where the aim was to determine the basic design parameters that should be used for ecological toilet prototype. The second phase is the development of ecological toilet prototypes, which are then tested in terms of their level of acceptance/rejection by potential end users. The overall aim is to develop toilet prototypes that on the one hand mitigate the production of black water, whilst on the other are accepted with open arms by end users, and even preferred over the conventional toilet common to urban areas.

This paper studied the impact of free cash flow and capital structure on the performance of the company. It is based on the theories of the free cash flow and the capital structure, combined with the actual situation of China, using different property listed corporations’ sample, makes an empirical study on the impact of free cash flow and capital structure on the performance of the company. The result shows that on the one hand, having more free cash flow will cause negative effects on the performance of corporation, on the other hand, with the increase in liabilities financing, the listed corporation's performance fall.
