Lord of the Plants:
Death Metal Eco-Baron Rewilds Irish Estate

Randal Plunkett, the 21st Baron of Dunsany, strides out of his Irish castle in a T-shirt bearing the name of death metal band "Cannibal Corpse" in bloody lettering.

In the distance, a russet-coloured stag appears for a moment, before dissolving into the 750 acres (300 hectares) of ancestral estate Plunkett has surrendered to the wilderness -- almost half of his lands.

"I felt a sort of sense of duty towards the environment here," said Plunkett, perched on a decaying tree trunk sprouting a clutch of mushrooms.

"I'm a caretaker of this estate for this generation and the estate is not just the castle, it's also the land but it's also the environment," the aristocrat told AFP, his mane of shoulder-length hair rippling in the breeze.

Eight years ago, death metal fan Plunkett, whose family have presided over Dunsany Castle northwest of Dublin for nine centuries, began his "radical" rewilding project.

The 38-year-old vegan, an unlikely successor to ancestors depicted in sober portraits lining the walls of the grey stone castle, evicted livestock and dismissed lawnmowers to allow nature to take its course.

Now, the results are plain. The ultra-rare pine marten has been spotted. Otters and red deer thrive.

Skies are jammed with birds: buzzards, red kites, peregrine falcons, sparrowhawks, kestrels and snipes.

Plunkett says a woodpecker has been sighted in the area for the first time in a century.

Beyond the castle crenellations, the lawn is transformed into a swirling morass of 23 species of grass, fizzing with insect life.

Plunkett lends a hand here and there -- planting 2,500 trees last year was no small feat -- but mostly he is hands-off.

"As I watched it, I began to understand what the land was doing," he said after trudging across a field of knotted undergrowth in a faux leather jacket.

"It became a rewilding project," he said, as two Jack Russell terriers named Beavis and Butt-head gambol around his vegan-friendly Doc Martens boots.

Analyze the following statements and mark T (True) or F (False):
(  ) In the first paragraph, the word bearing acts as a present participle that introduces a reduced relative clause describing the T-shirt.
(  ) In the sixth paragraph, the verbal forms evicted and dismissed function as past participles in a passive voice structure where the subject receives the action.
(  ) In the phrase occurring in the tenth paragraph, the word fizzing serves as a present participle that modifies the noun morass, describing its active state.
(  ) In the clause appearing in the twelfth paragraph, the word what represents a relative pronoun that functions as the object of the verb doing and cannot be substituted by the word "that" in this speciÍic syntax.
Which alternative CORRECTLY fills in the parentheses above, from top to bottom?

A new William Hope Hodgson blog

Welcome to Hodgsoniana, a new blog about the life and works of author William Hope Hodgson (1877–1918). The aim of this blog is to provide a home for articles and new research on Hodgson, details of Hodgson-related happenings, and just generally act as an up-to-date (hopefully) resource that’s open to anyone interested in this remarkable literary figure. At time of writing, there is a lack of other active websites covering this subject, which is why starting a blog seemed a worthwhile endeavour. At the very least, it gives me a place to post some Hodgson-related thoughts and findings I’ve been meaning to write up! My hope is that others may be moved to contribute also.

Before going any further, I want to recognise the work of the late Hodgson scholar Sam Gafford, and in particular his excellent Hodgson blog williamhopehodgson.wordpress.com. I first stumbled upon Sam’s blog back in 2016, and his work opened my eyes to the depths and complexities of Hodgson’s history and writings. I entered into brief correspondence with Sam at that time, and his enthusiasm and encouragement were key factors in starting me on the path of pursuing my own Hodgson studies.

Sam Gafford sadly passed away in 2019, leaving his site dormant. It remains a valuable treasure trove of information, and I will certainly aspire to follow Sam’s example in exploring and documenting all matters Hodgson.

2027 will see the 150th anniversary of William Hope Hodgson’s birth. There is still much to discuss regarding his work, and many areas of his life remain obscure and in need of further investigation. I hope this site can help in encouraging and chronicling such efforts.

Round Up: New William Hodgson Editions

    The British Library's Tales of the Weird series has arguably been leading the charge in the mainstream reissuing of classic and obscure weird works, issuing thoughtfully curated collections on a near-monthly basis since July 2018. At time of writing, there have been over 60 volumes released under this imprint, with many more lined up.
    Not only was a collection of William Hope Hodgson's short stories an early inclusion (The Weird Tales of William Hope Hodgson, April 2019), but Hodgson is unique in having had two of his novels issued in the same line The House on the Border/and (October 2023) and The Níght Land (May 2024), both with an introduction by Ann VanderMeer. Only a handful of novels have been published in the Tales of the Weird series (the vast majority oÍ volumes are short story collections), so it is remarkable that two of WHH's novels have been chosen for inclusion.
    Penguin books have recently gotten in on the action, launching their own Penguin Weird Fiction range in October last year. Five books were published simultaneously - Hodgson's The House on the Borderland again being included - all with cover art "inspired by 1970s Penguin genre paperbacks". This isn't the first time Borderland has been published by Penguin: it was included as part of their (seemingly inconsistently labelled) Red Classics / Gothic Classics series back in 2008. At any rate, it's great to see Hodgson back in print with such a high profile publishing house.

In writing, passive voice is a strategic tool used to control focus. Based on the text, analyze the statements below:

I. The phrase "being included" (third paragraph) uses a passive structure to emphasize The House on the Borderland as the recipient of the action, while the agent (the publisher) remains implied.
II. "Were published simultaneously" (third paragraph) employs the passive voice to shift the focus to the books themselves, rather than the act of the publisher.
III. "Many more lined up" (first paragraph) functions as a reduced passive structure, highlighting the status of future volumes without naming the specific arranger.
IV.The phrase "launched their own Penguin Weird Fiction range" (third paragraph) is an example of the active voice, where the subject (Penguin Books) clearly performs the action.

To answer question, read the text below.


The Language of Performance

    Well, the word “performative” is generally meant as an insult. It’s meant to trivialize and indicate that someone is play-acting or “faking it.” It suggests that someone is only doing something to be seen doing it, and not because it represents a sincere interest or enjoyment.


    This is one of those situations in which metaphors are overextended, and language distorts rather than describes natural human behavior. It is normal for our species for men and women to “perform” acts to impress both our own sex and the opposite sex. Males and females have different sex “roles,” and we “perform” acts to satisfy those roles.


    The language seems to “portray” us as “actors performing roles” and implies that we are all essentially “lying” or “faking.” This is the kind of wordcel wordtrap that lends itself to Marxist gender theory ideology and postmodernist thinking.


    “Nothing is real, everything is fake. Everything is a performance.”


    That’s a frame, but it isn’t the whole picture.


    Men are primates. We imitate each other. Monkey see, monkey do. And yes, we do things to try to impress each other. You can frame that in a way that seems trivial or superficial, but it is also foundational to human nature and social hierarchy.

The author uses the passive voice sparingly and primarily for definitions (e.g., is generally meant), while shifting to a consistent active voice to build his core argument. Considering this stylistic choice, analyze the statements below:



I. Passive constructions tend to obscure the agent of the action, creating a sense of detachment.


II. Active verbs (such as those appearing in the second and third paragraphs) assign clear responsibility to the subject, making the critique feel more direct and assertive.


III. The use of active voice emphasizes that actions (like those mentioned in the fourth paragraph) are deliberate and intentional rather than passive occurrences.


IV. Extensive use of the passive voice would weaken the punchy, authoritative tone of the argument established throughout the text.

Advanced Dynamics of International Business Strategy


In the era of hyper-globalization, international busi ness strategy has evolved into a highly sophisticated discipline characterized by the orchestration of cross border value creation under conditions of uncertainty and institutional divergence. Multinational enterprises (MNEs) must navigate complex configurations of global value chains (GVCs), optimizing location-spe cific advantages while mitigating transaction costs, as articulated in Transaction Cost Economics.


A central theoretical lens in this domain is the Eclectic Paradigm, which posits that firms engage in foreign direct investment (FDI) when three conditions are satisfied: ownership-specific advantages (O), location specific advantages (L), and internalization incentives (I). These determinants collectively inform entry mode decisions, ranging from wholly owned subsidiaries to joint ventures and strategic alliances.


Institutional theory further underscores the impor tance of isomorphic pressures—coercive, mimetic, and normative—that shape organizational behavior across different jurisdictions. Firms operating in emerging economies often encounter institutional voids, charac terized by the absence or underdevelopment of inter mediaries such as capital markets, legal enforcement mechanisms, and regulatory agencies. In such contexts, firms may adopt non-market strategies, including polit ical lobbying and network-based relational contracting, to compensate for institutional deficiencies.


From an operational perspective, supply chain resil ience has become a critical strategic priority.


Concepts such as just-in-time (JIT) inventory manage ment are increasingly being reevaluated in favor of just-in-case (JIC) models, particularly in light of disrup tions stemming from events like the COVID-19 pan demic. Firms now emphasize redundancy, nearshoring, and diversification of suppliers to enhance robustness against exogenous shocks.


Financially, exchange rate volatility and cross-border capital flows introduce significant risks. Firms employ sophisticated hedging instruments, such as forward contracts, options, and swaps, to manage foreign exchange exposure. Additionally, transfer-pricing mechanisms are utilized not only for internal cost allocation but also as tools for tax optimization, often scrutinized by regulatory authorities for compliance with the arm’s length principle.


Digitalization and Industry 4.0 technologies—including artificial intelligence, blockchain, and the Internet of Things (IoT)—are transforming international operations. These technologies facilitate real-time data analytics, enhance transparency in supply chains, and enable predictive decision-making. However, they also neces sitate compliance with divergent data localization laws and cybersecurity regulations across jurisdictions.


Sustainability and ESG integration are increasingly embedded in corporate strategy through frameworks such as carbon accounting, circular economy models, and impact investing. Firms are now expected to align with global standards like the United Nations Global Compact, ensuring adherence to principles related to human rights, labor, environment, and anti-corruption.


Ultimately, competitive advantage .........................  international business is contingent ........................... a firm’s ability to integrate strategic, operational, financial, and technological capabilities while remaining adaptive ................... an evolving global ecosystem marked ....................... volatility, uncertainty, complexity, and ambiguity (VUCA).

Study the sentences below and decide if they are true ( T ) or false ( F ), based on their grammatical accu racy, vocabulary use, and structural correctness.

(_) There are four prepositions missing in the final paragraph. The most appropriate sequence is: in; on; to; by.

(_) The sentence Hedging instruments are employed by firms to manage risks is correctly written in the Passive Voice.

(_) The word nearshoring, in the fifth paragraph, refers to moving production overseas.

(_) Mitigating transaction costs most nearly means reducing transaction costs.

(_) In the sixth paragraph, the expressions not only and but also, form a correlative conjunc tion pair used to connect two related ideas.

PROFESSOR DE LÍNGUA INGLESA:

THE DIGITAL FRONTIER OF FIDELITY

The Nuances of Micro-cheating: Social Practice or Digital Paranoia ?  


In the contemporary landscape of interpersonal relationships, the ubiquity of social media has recalibrated the traditional parameters of faithfulness. The emergence of the term "micro-cheating" serves as a testament to this shift, encompassing a spectrum of subtle, digitally-mediated behaviors that, while devoid of physical consummation, suggest an emotional or erotic redirection. Such actions— ranging from the seemingly innocuous "double-tap" on an expartner’s archived photograph to the deliberate concealment of encrypted message threads—occupy a contentious "grey area" that challenges the binary definition of infidelity.  

From a socio-psychological perspective, micro-cheating is often interpreted not as an isolated act of betrayal, but as a symptom of the "validation economy." The digital architecture of modern platforms encourages a constant pursuit of external approval, where a notification can function as a dopamine-inducing ego boost. Consequently, the ambiguity of intent becomes the focal point of the debate: is the digital interaction a legitimate exercise of social autonomy or a covert erosion of the primary partnership’s exclusivity? Proponents of the concept argue that the "secrecy criterion" is the ultimate litmus test—if an interaction is intentionally shielded from a partner’s view, the threshold of trust has likely been breached.  

Conversely, skeptics caution against the pathologization of digital sociability. They argue that the expansion of the "cheating" umbrella to include minor online interactions fosters a climate of hyper-vigilance and domestic surveillance, potentially undermining the very foundation of trust it seeks to protect. By labeling these behaviors as "micro-infidelities," we risk imposing a panoptic gaze on our partners, where every "friend request" is scrutinized for subversive intent.

For the language educator, this phenomenon provides a rich semiotic field for classroom reflection. Aligning with the National Common Curricular Base (BNCC), the study of such themes transcends mere grammatical decoding. It invites students to engage in "multiliteracies," analyzing how meaning is negotiated across digital platforms and how language (visual, verbal, and symbolic) shapes social ethics. In this sense, the English language is not merely a system of signs to be mastered, but a tool for critical agency in a globalized, hyper-connected world.

Students using A.I. over humans to learn English (23rd December 2024)


        More and more students in Japan are using artificial intelligence (AI) to learn English and other languages. The language learning app Duolingo conducted a survey on how students study languages. More than 4,700 Japanese students answered questions about their language-learning habits. The survey found that the number of people using ChatGPT and other AI tools increased by more than 80 per cent in 2024. AI was particularly popular with younger people. The researchers said more young people used AI than took face-to-face lessons. However, some people in their 20s were not totally happy with AI lessons. They said AI lacked natural responses and was a little boring.


        Duolingo said: "We're in the midst of an AI revolution.…Technology has long had an impact on language learning." It found that apps were the most popular method in Japan to learn languages. English was the most studied language, followed by Korean. People are studying Korean "to understand the language as spoken by…favourite artists and celebrities." Duolingo said around 58 per cent of people who took the survey used language-learning apps. This was followed by video streaming platforms like YouTube and Netflix (37%), textbooks (36%) and online lessons (16%). The number of people going to a language school is decreasing. Just 13.8 per cent of people went to classes with a teacher.
