title: Spillover effects of sanctions on airlines

authors: Corbet, Shaen

abstract: To counter the escalating threat of direct conflict with rogue nations, the use of sanctions packages has become a preferred tactical response. However, although targeted, there are significantly elevated spillover effects that can generate sectoral damage. While the literature on sanctions has focused on analyzing the effectiveness and the impact on the sanctioned and sanctioning country, spillover effects have not been addressed in the tourism and travel industry. Based on behavioral decision theory and modern portfolio theory, this study states hypotheses and confronts two potential results derived from each theory regarding the way negative consequences of sanctions spill over into airlines. Using the aviation sanctions packages derived from the Russia-Ukraine war in 2022 in different regions worldwide, the results indicate greater spillovers flow into airlines than other aviation-related corporations, into big firms than small firms, and with significant differential effects on each analyzed region.

title: Taxonomic, biological, population dynamics and behavioural studies on sod webworms (Lepidoptera : pyralidae: crambinae and scopariinae) of some Waikato (New Zealand) hill country pastures

authors: Cowley, Jocelyn Marie

abstract: New Zealand has a rich fauna of sod webworms (Lepidoptera: Pyralidae: Crambinae and Scopariinae) which have been implicated in sporadic outbreaks of pasture damage. This study investigates sod webworms of south facing hill country slopes of some Waikato pastures. Four aspects are considered: taxonomy of the species present; some features of their biology; population dynamics of Eudonia sabulosella (Walker) (the most common species); and adult behaviour, especially flight.

Taxonomy is detailed for male and female adults (with accompanying genitalia figures) and for eggs, larvae and pupae where available. Nine species are involved: Orocrambus flexuosellus (Doubleday), and O. vitellus (Doubleday) (Crambinae); Eudonia psammitis (Meyrick), E. sabulosella (Walker), “Scoparia” bisinualis Hudson, “S”. Diphtheralis Walker, “S”. halopis Meyrick, “S”. philerga Meyrick and “S”. submariginalis (Walker).

A summary of meteorological data including soil moisture content, soil temperature, air temperature, relative humidity and rainfall is given for the main study sites. 

Life cycles and generation times with information on the duration of adult seasons are presented for each species. Habitats of eggs, larvae, pupae and adults are defined and selection of oviposition sites by female Eudonia sabulosella is investigated. Studies are made on food types, larval growth rates and adult reproductive maturity. Longevity of adults, mating frequencies and female fecundity (taken as the number of eggs found in dissected field collected females) are measured. Egg fertility and viability as well as egg incubation times are investigated.

Life tables are presented for Eudonia sabulosella on hill country pasture. Key factor analysis is undertaken to identify major mortality factors. Parasitism by Aucklandella geiri (Ichneumonidae) and arthropod and avian predation on sod webworm larvae are studied. Pathogen infection of E. sabulosella by nematodes (some of which were Steinernema bibionis Wouts et al.) and a neogregarine protozoan (Mattesia sp.) is investigated. Effects of the protozoan on host size (body weight and length) and female fecundity are measured. Median lethal doses of pathogen are presented for larvae and pupae. Methods of protozoan transmission are discussed. 

Adult flight activity is interpreted in relation to air temperature, humidity, rainfall, barometric pressure, wind speed and direction, cloud cover, lunar cycle, reproductive state of the adult, time of day, species and sex. Susceptible pastures are indicated. An understanding of some of the factors affecting the sporadic (temporal and spatial) occurrence of sod webworm infestations has been gained.

title: Feminist geographies in Aotearoa New Zealand: cultural, social and political moments

authors: Adams-Hutcheson, Gail

subjects: Social Sciences

abstract: Aotearoa New Zealand is a nation of promise, potential and enigma: it was the first country in the world where women gained the vote in 1893 and now boasts the youngest woman world leader in 2017. It is also a postcolonial nation where structural racism, homophobia, and sexism persist, yet it has also given legal personhood to a river. Our Country Report foregrounds Aotearoa New Zealand feminist geographic scholarship that responds to, reflects, and sometimes resists such contrasts and contradictions at the national scale. We employ the lens of the 2017 national election to critically engage with current gendered and indigenous politics in the country. Analyzing these politics through three ‘feminist moments,’ our paper highlights the breadth and scope of current Aotearoa New Zealand feminist geographic scholarship and directions.
